This is Andreessen trolling to get traffic on their new publication website... Obviously technology is not saving the world. Sure we made a vaccine for a disease that was bad. But technology is mostly responsible for propagating it in the first place.

And climate change, you know.

EDIT: also on HN front page, fully autonomous killer drones are being mass-produced.

hmm, I'm not sure I agree with all points made in this post, but surely two things can be true at once? In other words, yes technology introduces problems (possibly the pandemic, as you stated), but might it not also provide the remedy?
>> yes technology introduces problems (possibly the pandemic, as you stated), but might it not also provide the remedy?

Sure, but even with the "remedy" we still had 600k deaths in the US and 3.8M globally. Not to mention the other problems caused by technology that are don't have a remedy yet, aka Climate crisis. I do agree with the comment above that we can't technology our way out of the climate crisis.

If you want to get super pedantic about it.. "Technology" doesn't do anything.

Humans do stuff, using technology. Some of it good, some of it is bad.

So it's really up to us, humans, to save the world. Or destroy it.

I don't want to get super pedantic about it.
You might be in the wrong place then. ;-)
Exactly, humanity will not be able to "technology" itself out of the climate crisis. There's no better carbon removal technology than our most efficient trees.
Even were that true we'd be better off with fusion-powered stacked greenhouses of them.
This statement denies reason.

There are plenty of ways in which we can technology our way out, even if we accept your premises (which, to be clear, I don’t but I’m willing to play ball).

Indeed, our only option – save for some type of genocidal movement – is to technology ourselves out of the climate crisis.

1. Engineer trees that store more carbon in denser and long lasting root systems

2. Create drone systems to plant and maintain tons more trees

3. Improve energy capture technology to reduce our net new greenhouse gases

4. Create more efficient motors for the same reason as above

5. Create new recycling technologies so we can reuse more of the stuff we already have without mining more

6. Speaking of raw material acquisition, we can mine asteroids instead of our own planet

7. Transition more activities online to reduce the need for physical travel for more things

8. Hell, move more business to the internet to reduce the environmental footprint of office space

Literally this list can go on and on. Technology is the only thing that fundamentally improves the trajectory of human society.

It would be very simple, fast, effective and not costly to use airliners with sulfur added to their fuel to increase earth's albedo. Problem solved. Of course we don't want to do this but it is an option.
Trees use the C3 pathway. There are much faster-growing plant species (for example bamboo, switchgrass) that could be incorporated into a BECCS process.
A technology creates externalities. Another technology neutralizes those externalities.

Given that we're unlikely (or unwilling) to put technological genies back in the bottle, what else can we hope for?

More responsible development & deployment of technology to avoid externalities in the first place?
Jon Stewart just made that point yesterday too:

“I think we owe a great debt of gratitude to science,” Stewart said. “Science has, in many ways, helped ease the suffering of this pandemic, which was more than likely caused by science.” (1)

I disagree with regard to climate change though because that externality has so far been a net positive for humanity and we can solve the downside. Yes, technology enabled us to dig up and burn buried carbon at scale sufficient to alter the climate, but that's what lifted billions out of poverty and eliminated starvation in much of the world. We'll solve the negative externality with renewable energy, clean nuclear energy, carbon capture, improved manufacturing efficiency and materials, etc.

1) https://news.yahoo.com/jon-stewart-endorses-lab-leak-1305162...

Easing starvation enabled more people to have offspring and that fact likely cause a swing in population which increased demand and use of fossil fuels.

The possible outcomes of a a runaway population living on a planet with a runaway climate are likely harder to predict than a simpler and smaller system.

I certainly do hope we can solve our problems with technology, but it will take concerted effort and unified attention to do so.

> which was more than likely caused by science

This is absolutely not true. There's zero evidence of a lab leak.

>Moderna, a product of the American venture capital system

Moderna got a government grant to do the mRNA work didn't they? Seems a product of public investment.

https://www.pbs.org/newshour/health/years-of-research-laid-g...

https://www.usatoday.com/story/news/factcheck/2020/11/24/fac...

https://investors.modernatx.com/news-releases/news-release-d...

No, they got an enormous amount of VC money for years. They reached a $1 billion valuation in just two years after founding (2012), faster than Uber/Dropbox/Lyft etc did.
Ok, but ...

https://seekingalpha.com/news/3609955-moderna-failed-to-disc...

And Derrick Rossi's research was publicly funded which led to creation of Moderna...

https://en.wikipedia.org/wiki/Derrick_Rossi

> Rossi based his developments on the results of Katalin Karikó and Drew Weissman on mRNA. He succeeded in finding investors for his plans to transfer these findings into new medications and vaccinations by founding Moderna

This is a tale as old as time. Government funds labs which invent and discover. VCs then fund companies to exploit and make money off publicly discovered work.

In the real world, both government grants and VC funding create great things.

If your political views make you want to diminish the importance of either, then perhaps it's time to update those views.

I'm trying to create a more balanced view. Andreessen made a claim that is completely false.

> Moderna, a product of the American venture capital system -- Andreessen

Where is he talking about the importance of government grants?

Yep this. The actual nose to the grindstone basic research work is often publicly funded but the VC fundraising bragging is often things like jets and swanky offices. The un-sexy work of doing basic research is not something capitalism handles well at all and we expect the government to subsidize it so the VCs can walk in, claim the work of their own, claim it was done via capitalism and the VC process, and then sell themselves as our saviors by creating media outlets that serve them. This is very dystopian and anti-government.
You're taking a pretty pessimistic view of the funding and R&D process. A good idea with initial funding by the government is useless if the VC funding doesn't bring the idea to the finish line. The government can't afford to (and shouldn't) fund every good idea to their finish line.
It's not pessimistic, just a fact of the R&D process. Public takes the risk, reward is privatized. Otherwise the VC model wouldn't work since most research doesn't fall within the horizon of a VC fund's lifetime.
That's how it's set up to work, government does the early work because it's not profitable for a company, we all pay into that work so we have the new technology sooner.

See: the internet, railways, computers, everything.

"Technology has become the idol of our society, but technological progress is—more often than not—aimed at solving problems caused by earlier technical inventions."

"Interesting possibilities arise when you combine old technology with new knowledge and new materials, or when you apply old concepts and traditional knowledge to modern technology."

Quotes from https://www.lowtechmagazine.com

You could say tech fosters a dependency on itself by people to sustain itself.
Isn't that the case for anything though? New problems only occur because of a previous change, and change usually only happens due to technology
I opt for technology rather than leading a nasty, brutish and short life.
I do not read something like that out of that quote.

Vaccines, emergency medicine, construction or farming equipment, all these things that make life easier, healthier and longer are not what GPs comment was about.

It talked about technology that was needed to fix problems created by earlier technology (think: someone has to write an ad-blocker because someone else optimized distributing advertisements).

Um, these technologies enable a larger human population, which then causes problems. Tractors enable ever larger tracts of the best land to be devoted to farming, to enable a larger population, to need more land to cultivate, etc.
This presupposes two questionable assumptions: that you have any choice in the matter, and that technology itself isn't the thing that is making your life nasty, brutish, and short.
Before the industrial revolution 25% of deaths were homicide.
Humanity has starved, struggled and regularly died in mass for millenia.

Now the population is 100 times larger than it was a few centuries ago, and more and more people are living in a post-scarcity society.

And yes, thanks to all the pioneers, entrepeneurs and geniuses that took an idea or insight into a mass market product. They are who truly deserve the credit.

What if all this is because we took a giant environmental credit that we won't be able to pay back? It's hard to argue that child mortality dropped, literacy increased and so on, but at the same time we are facing existential threats due to warming, lack of water, loss of biodiversity and so on.

We are also enjoying a relatively peaceful period (despite what's happening in Syria and tens of other places) on a global scale, but history shows that every single global conflict gets more deadly. Will we survive WW3?

Let's not prise the day too early.

I don't fall for environmental sensationalism

The world is in it's most "livable" state ever

No, let's absolutely praise it.

Because the existential threats only exist because of political malfeasance. This has never been a technological problem: even the potentially disastrous consequences of climate change only really manifest because of - again - politics. Because governments won't spend to protect their own citizens, because of corruption and greed.

Little has changed on that front in thousands of years. Technology enabled almost everything we have now - even those improvements in governance we got (i.e. mass communications and the telegraph made coordinating large empires and alleviating local resource shortages via logistics possible).

Technology is neither source of good nor evil. Just like a hammer ain't to blame or prise. It's about its application and how tech is developed and applied is decided based on "politics" if you want.

However, ever-evolving technology leads to globalisation and acceleration of processes. With shitty tech we can make lots of mistakes and pay small, local consequences. Shitty nails result in a shitty coffin. Shitty fridges result in an ozone hole. Our margin of error for doing the "politics" right is shrinking every day.

We have been stealing from the future to pay for the present, as long as we keep stealing more and more from the future it'll be fine!

Or be forced to not cheat and invent ways to live within our means

Unfortunately, the future is now.
> history shows that every single global conflict

Er, not to be pissy, but isn't that a sample size of two?

It's your right to be pissy. Let's drop the "global" then.

I counted 18 wars with upper deaths range above 1M between 500BC and 1800AC. There were 29 of them after 1800. I didn't bother to sum the casualties. Full list:

https://en.wikipedia.org/wiki/List_of_wars_by_death_toll

There are a lot more people today, too. Of course war death tolls will be larger.
this got me curious as I wasn't sure how much is "a lot more". Turns out the population in the year 0 was 190M so there are 40x more people now [0].

Anyway, according to the previously cited wikipedia article, the Three Kingdoms War, the deadliest ancient conflict, took toll of 40M people. but that happened over 96 years. That's 416k per year and 0.2% of global population at that time.

WW2 caused 14M deaths per year which was "just" 0.07% of global population.

Not sure how accurate these numbers are.

[0] https://ourworldindata.org/world-population-growth

Fair enough. It also adds to your point that the earlier wars tended to be a lot longer than the later ones, meaning the intensity of the killing has been increasing, eh?

FWIW I'm usually on the doom-and-gloom side of the argument (benefit vs. hazard of tech).

I think it's the opposite. Though the casualties in earlier large conflicts are numerically smaller than compared to WW1/WW2 etc, as a percentage of the population involved, they're higher, no?
Tl;dr: billionaire wanks off over the merits of venture capitalism and half assed technological solutions to social problems; wants you to do the same.
> Permanently divorcing physical location from economic opportunity gives us a real shot at radically expanding the number of good jobs in the world while also dramatically improving quality of life for millions, or billions, of people.

This doesn't seem consistent with what is happening in A16Z's own backyard. Either Marc knows something we don't or this is unwarranted hyperbole.

Well, let's run that through the VC->English converter:

"We hope to lay off all the first world engineers living in Silicon Valley and hire exclusively the cheapest possible people living in the cheapest countries. We can hire twice as many bodies (double the good jobs, just not in the USA!) for one-tenth as much money, pocket all the profits, and if anyone complains (perhaps all the laid off engineers) we can talk about how we're raising people out of poverty, how dare they complain."

My version is admittedly not as flowery as the original.

Or maybe: "Some of our partners want to move to Texas. All the money they will spend there will move 10s of people out of poverty in Austin."
Don’t conflate “cheaper” with “cheapest”.

Ideally, it would be the same talent, in cheaper regions now. Cut out the landlord middleman.

I know, the worker is getting less, the company is simply subsidising a cheaper home. But many workers, not all but significantly many, will prefer a better lifestyle outside of cities.

When you fire 500,000 highly-paid workers, and distribute half their pay to dramatically raise the wages of 5,000,000 workers in very poor places and the other half to 50 extremely rich capitalists, you've "expand[ed] the number of good jobs in the world" and "dramatically improv[ed] the qualify of life for millions [...] of people".

It's hard to even argue against, ethically—except that, conveniently, the people most vocally pushing it always seem to be in a "heads I win, tails you lose" position and are never the ones who will lose anything to make it happen. Usually quite the opposite.

Andreessen's posts are strongly biased towards what is beneficial for his position.

I have read a lot of his posts since 2008 and before. They are intelligent and insightful, but in hindsight lot of them were not best advice for founders/readers but best for the VC.

Same goes for pg. And most other people, I suppose. It’s hard to forgo self-interest.
One's measure of these VCs changes quite distinctly when you change from viewing them through the prism of leaders of the industry to viewing them as self-interested marketeers acting as gatekeepers of a subset of wealth with the express purpose of their working role as the endeavor of inflating their own wealth.

They haven't gone hungry in quite some time, and it's really been showing more and more as time goes on and their memories of when they started out are fading.

The same is true for any VC blog, it’s marketing - to both investors and founders. But you can be both biased and insightful! I found this essay very inspirational, we truly are living during exceptional times

If you don’t take into account bias and agendas when you read anything, you probably won’t be a great founder.

indeed. I feel it's a lot more difficult to agree with the `SV elites` (az, pg, etc.) recently, wondering if I'm too old or they live in their own rdf.
The world looks different from a throne.

There was a great comment on reddit once that calculated a $50,000 car costs about the same to Jay-Z as a tank of gas does to a median person. That’s a huge difference in perspective.

Someone like az, pg, etc probably sees higher daily variations in their stock portfolio than my annual salary. Imagine what life is like when $200k rounds down to “daily noise”?

For me, after lots of saving, those fluctuations are in the $300 range and even that changed my perspective and way of thinking. Very different feel than when I was starting out and having $300 felt like unimaginable wealth.

For comparison, a $500 unexpected expense would bankrupt 41% of americans.

"Moderna, a product of the American venture capital system, created the first mRNA COVID vaccine within two days of receiving the genetic code for COVID by email."

I love how the lab leak theory is now mainstream but everytime I brought that up along with where the sequencing came from I looked like a crackpot.

That email and sequence came directly from China.

Look at the Jan 11 note here: https://www.modernatx.com/modernas-work-potential-vaccine-ag...

Please explain why anything said above is not factual rather than downvote?
I believe you're being down voted because you haven't said anything of substance. You mentioned an anecdote and how the sequence reached Moderna. If you're implying something, maybe say that instead of baiting people to guess your position.
He seems to ignore Florida, Texas, etc who did just fine before the “technology” was ready.

Edit sorry to offend but his false dichotomy of five years of lockdown without a vaccine just rubs me the wrong way.

I love me some technology, don't get me wrong.

But if the lab-leak hypothesis turns out to be correct than technology is undoubtedly the very thing that put the world in peril in the first place, as far as COVID-19 is concerned, before you even consider increased air travel and globalization encouraging/increasing the instant spread of modern pathogens.

if the lab-leak hypothesis turns out to be correct than technology is undoubtedly the very thing that put the world in peril in the first place

Whatever lessons we might learn if it were to turn out that COVID is a human-made experiment are lessons we should be taking heed of even if it isn't.

Absolutely! Not to mention that we already have very strong evidence that dangerous pathogens have escaped from other labs in the past.
Maybe this will play out like nuclear technologies. Incredible potential for good also means incredible potential for bad. For nuclear, the good was roughly limitless energy at very low environmental cost and low human labor. The bad was nuclear weapons material and nuclear accidents. After the accidents, the nuclear industry in advanced countries basically goes into sleep mode, maintaining existing assets, but unable to expand or grow. Perhaps the lab-leak will have the same result for biomed sciences. Accident leads to millions or tens of millions of deaths and industry must go into stasis. You might say the gain-of-function research is sufficiently differentiated from normal biomedical research that they don't get grouped together. But I doubt it. You can probably do gain-of-function in any old bio lab. The only thing stopping it is the good intentions of the users.

The effort to cause massive societal disruption and destruction is so much easier for bio based weapons than for nuclear. In nuclear, you need so many things to line up if you're building a weapon from obtaining the requisite materials, enrichment, weapon design and electronics, delivery vehicles; and so many things to go wrong if you are going to have a consequential nuclear accident. In contrast, bio weapons can be developed in a dinky lab, deployed, and then self-propagate worldwide.

Ironically, it is technology that gets the world out of these perils, too. I get your point though, nature could only fuel so much growth before it irreversibly changes course and stops sustaining life as we know it.
Eh, not really more so than usual. We've probably had fewer the last 100 years due to better tech and science. Pandemics have always been a civilizational challenge, often caused by technology, greed and hubris. Making it in a lab (unlikely, but theoretically possible) and transporting it by air instead of doing both in the hull of a galley is just a new twist that enabled greater scale.
Technology accelerates change at an accelerated rate. While this could be beneficial to society, the main driver of innovation or creation of technology remains capitalism.

Guy Kawasaki has made some great points about how a business, founded in capitalism, should find purpose to make the world a better place. In many cases those changes brought on by a given technology isn't obvious until the technology has been adopted in a widespread way.

Facebook may "help" people connect and discuss important matters, but it also created a conduit (deluge) of information which hijacks people's attention away from things that may serve them better in the long run. It's when technology like Facebook, Twitter and other social media platforms push data to us that we give way, emotionally, to the influence.

When emotions get involved, attention is diverted.

I didn’t read the post, just checked the comments. 23 out of 23 has negative tone.

A tech magnate raises the bar. Goes from ‘better’ to ‘save’. Technology is heaven, himself is a god. Perhaps should be better, for all of the humanity, to tone down this voice a little bit.

Otherwise it leads to idiocracy.

I found this article to be excellent, unlike most commenters here, perhaps because I had not heard of the author before. Laying out how so many parts of the economy, health system, educational system, and entertainment industries used relatively new technology to keep on' running is a very interesting observation, and it is fascinating to see it all laid out in one concise piece like this.
In reality humans have a complicated relationship with technology. As much as it promises to save the world, technology is also what is increasingly over the last couple centuries threatening to destroy the world and our species. So technology may be saving the world, but largely from itself.
Do you want a nasty, brutish, and short life living in cave instead? Because everything better than that came from technology.

And even stone age man had sufficient technology to extinctify other species.

You've at least twice on this story borrowed from Hobbes to dismiss posts expressing what amounts to, "maybe our relationship with technology is a bit complex, and a mixed bag, and worth some examination and consideration", as if you were responding to posts advocating full-on anarcho-primitivism. Why?
Technology enabling unsustainable practices goes all the way back to the bow and arrow. Not just the last couple centuries.
Ah—you object to framing it as a new problem, then? That makes sense.
a man's got to do what a man's got to do. talk up his book. cheerlead the workforce towards the next big thing etc.

the fact is an idiotic strand of rna has defeated us all. our collective intelligence crumbled. toilet papers and flour disappeared from shelves and that was just the start.

the billions of "supercomputers in our pockets": defanged, untrusted, unusable as a tool in the fight against the most simplistic of spreading algorithms

the billions of "platform" users: amplifiers of deep and justified distrust, preventing even the miracle of quick vaccines (which was by no means a given) to reach the masses

to be sure the systemic failure we witnessed is by far not just a "tech" or even V/C failure. you can try put lipstick on a pig. but "tech" was measured and came up short.

for any thinking techie out there (and there are many) a time to reflect, then act

"we thought the world was gonna end, it didn't because we saved us!" ... or, possibly, the world wasn't going to end in the first place, and y'all selling fear caused much of the harm you're so proud to have mitigated now...
“Knowledge work simply kept going on” - or maybe it simply is irrelevant? We’re just shuffling papers, what really matters is on what car we spend our money on, or what chinese crap we buy off amazon.
(With apologies to those that have heard it before) Bucky Fuller (an engineer) calculated that we would have by sometime in the 1970's all the technology necessary to create a kind of secular utopia if we applied our knowledge to solving our problems efficiently.

We could each work for two years and then retire having paid for the rest of our lives during that two-year career.

This happened more or less right on schedule (the technological advances, not the social/economic shift.)

Ergo, our problems now are not physical, they are mental/emotional. The only thing holding us back is ourselves and our (regressive or at least complacent) attitudes and beliefs.

- - - -

As an aside, "But yet, one gets the sense that Pandora’s box has been opened." That's not the right metaphor. The box Pandora opened was filled with evil demons.

Aside from the usual hedonic treadmill explanation, a lot of our problems with ever-inflating costs are due to competition for limited goods—especially those conferring advantage to our kids. Houses in good school districts, private school slots, various expensive activities that make getting into top-tier colleges more likely, et c.

Two-income households? Now you're richer? LOL no, just more money lost to zero-sum competition. Making retirement contributions voluntary? Oh great, now my competitors who choose not to save well can out-compete me for advantage for their children now, thanks a bunch. And so on.

FWIW Bucky meant that we could eliminate poverty and starvation, not that we could supply unbounded luxuries.

The rise of non-fungible tokens shows that folks will find ways to compete for limited resources, even if they have to dream them up.

Arms races, the growing search space for attack asymmetries, and the ever increasing mobility of capital paired with the inherent centralization of returns due to computing.

Housing price inflation and advantages to children are examples of figurative arms races. And you're right, it's destroying our societies.

Cyberwarfare and military buildups are actual arms races. Defence is getting more and more expensive. Globally, cybersecurity spending is going north of $1T, and I doubt it will ever decrease.

What we have is a coordination or alignment problem. If we could get values aligned enough to coordinate more effectively we wouldn't have such an insane world.

And as an aside, I highly doubt we'll be able to solve the alignment problem with AI. Either the AGI is going to want to coordinate due to its own character, or it won't, and short of putting it in some unobservable virtual machine and testing it to, say, see if it would give up its life for its friend; I don't know what else you could do to really know how deeply embedded its values are.

There are a lot more people alive today than in the 1970s.
True. So we work for three years, eh?

More seriously, you're correct that population pressure is one of the main problems that could derail a techno-utopian scenario. Fortunately, population seems to be leveling off.

I like to joke that the Amish are the "meek" who will "inherit the earth", as they are fantastic farmers and still have large families. But there's an element of truth to the joke: if most folks stop increasing their own population, but a few (like the Amish) don't, then in the fullness of time they would eventually, uh, overrun the rest of us regardless of any particular technological change.

The ultimate question for humanity is what happens when we can fix this. It will first start with extreme mental issues ( addiction, the suicidal, the pedophiles). But eventually it gets to "Should children born with a desire to be the best at any cost be 'fixed' to remove that desire?" Are we still human when we remove the tribal and lizard brain desires that dominate human activity today?
The only reason we're not all chilling out and relaxing is the "rat race".

We're not competing with the animal kingdom anymore. We're competing with other humans.

Good luck getting all humans to stop trying to dominate/outdo each other. It only takes one and the race is off again.

Half joking take : what "saved the world" (the deal is hardly done, unfortunately) was a mix of technology, incredible dedication, and vast amount of printed money.

Would medtechs have succeed if they were not sure governments would pay "whatever it costs" for vaccines ? Not sure.

Would people have paid Disney+ without government help funds? Maybe less.

2020 was probably better handled than 2008 here.

However, I'm conviced the healthcare workers would have made their insane efforts no matter what the policy ; and the governments might have failed them so far. We'll have to do better for them next time - they saved the day, in the end.

So, now covid 19 is on the list of examples (like Manhattan, Apollo, etc...) where "printing unlimited amount of money to have dedicated people solve a problem" worked.

When do we start doing that on climate change ?

3-6 months after it begins to affect the ultra wealthy would be my guess.
Not yet.

Much of the world doesn’t yet have access to vaccine.

Let’s remind ourselves that, these technologies are products of decades of scientific effort funded by public. Many of these projects never pan out (public pays for risk). VC and private sector join only when technology is sufficiently mature, and will pocket the lion share of the profit. Even within the private sector, gains and risks of technology are not widely shared. This is how it works, but let’s get the credit assignment right.

Of course, technology also creates problems that are often passed to public (socialized risk, private profits), until the next iteration of the above process. Environmental damage is a case in point.

So, yes, science and technology are wonderful, but let’s share the productivity gains widely, and let us all contribute to the effort (directly, and through fair taxation and policies).

"What doesn't kill you makes you stronger" kudos to technology for making us stronger in the face of COVID-19
Don’t get me wrong, I love technology. But the other edge of the sword here is that the ability to text and Zoom and YouTube and DoorDash etc. is the only reason that lockdowns were even possible in most of the world. Without these tools, it would have unconscionable for policymakers to try to put millions of people on house arrest, especially if their class’ own livelihoods were liable to be as damaged as physical small business owners and workers. Andreessen is treating lockdowns as an inevitable natural force here rather than a policy decision with particular tradeoffs. In their own (unavoidable) way, these tools enabled lockdowns just as much as they helped people during them.
>> The best jobs have always been in the bigger cities, where quality of life is inevitably impaired by the practical constraints of colocation and density. This has also meant that governance of bigger cities can be truly terrible, since people have no choice but to live there if they want the good jobs.

This reads as if it's written by someone whose idea of a "big city" is San Francisco. SF is uniquely terrible among large American cities. Even other American cities aren't great compared to their international counterparts.

Density, even in those other not-that-great American cities, also affords a quality of life not possible in smaller areas. Easy access to cultural institutions, quality restaurants, music venues, events, public transit, and other things only possible with sufficient density.

As a parent of a small child in the city, I'm accustomed to having many other parents and children nearby to meet at the many area parks and playgrounds. In every suburban or small town playground we've been to, I've been struck by the absence of others. I'd much rather share playgrounds and have plenty of other children for my child to interact with than be limited to day care and the back yard, which seems to be the case in less-dense areas.

I also thoroughly enjoy and appreciate being able to walk and bicycle for errands and amenities, which is not possible in many less-dense areas.

It's possible a sufficiently dense but small city or town could provide these same qualities of life, but these communities don't seem to exist in America. Smaller areas just by their nature spread out, and even some larger cities aren't dense enough and are still car-dependent.
