Is it just me or are others also stuck in a I'm-not-a-robot-loop?
If it's cloudflare and you're in linux or a less than dominant browser, I've just relegated myself to adding the Privacy Pass extension... Which seems to help resolve the issue.
Michio Kaku is a smart guy, but I wouldn't call him a "Top Physicist"
He's a "futurist", who's explicit job is to make hand wavey, big, shocking claims. Historically, futurists have a less than random chance at being right about the future.

Also I would not consider him an expert in anything ML, though he probably has enough of the underlying math to get some things.

do you have anything to say about the points he's making, or just here to judge the person ?
I'm saying explicitly that the words that come out of Mr Kaku's mouth are noise, not signal. If he is right about something, it is in the way a broken clock is occasionally right. I agree with most of what he is saying personally, but that's not relevant.
Kaku is a media sensationalist; that class of person has a terrible track record. Futurists, that is, people like Aasimov, have an ok track record at predicting the future. Interestingly, early futurist predictions about digital tech were pretty good. For "physical" goods? Not so much. A plausible explanation of this discrepancy is that they didn't predict the breakdown in the historial trend of increasing energy usage. See the Henry Adams curve.
a "co-founder of string field theory" (citation from Britannica) sounds like a top physicist. What are your contributions ?
He might have been a “top physicist”, but it appears he has long since started phoning it in.

See the link to Aaronsons blog elsewhere in the thread for an example of the kind of drivel Kaku puts out, and why he shouldn’t be taken seriously.

string field theory is a a "field" of physics which is entirely theoretical and has no experiment data to back it up.... hard to imagine how even the top person in that field would be a top physicist given the large number of top physicists who are doing useful stuff like LIGO, CERN, etc.
And especially not in an article where he's presented as being against "media sensationalism"...

Compare the feeling of: "Top financial advisor Elon Musk warns against cults of personality, stresses importance of finance fundamentals."

I would describe Michio Kaku the same way.
I don’t know who you are or why you’d describe him this way, but your post doesn’t contribute to the discussion.
I dont think there's much to discuss about this article because Kaku's opinion on AI is worthless.

He is less a physicist than a parrot that is paid to repeat far fetched claims about whatever pop science thing is in the news.

Your comment seems to have been written by an untrained chatbot!
Computers are glorified abacus.
Exactly. Glorification can be pretty significant. Humans are glorified apes.
I don't know what is weirder. That Fortune is reduced to clickbait like this or that this was upvoted so much on HN.
time to start thinking about who (and what) is upvoting things on HN.
The most-charitable interpretation I can think of is that some folks are reading the title, thinking "I agree, chatbots are overhyped", and voting before moving on.

So they don't see the incoherence of the article because they never click, or else they don't have the historical context to see how it's bizarre to present Kaku as a voice against "media sensationalism".

Just dealt with a chatbot on DHL site the other day.

It was just a glorified countdown-to-chat with human customer agent. It was fine for that, otherwise worthless.

What's the best way to find out all of his past predictions, with the date he made them, and the result? I guess this is a question on all experts and talking heads, not just Kaku.

I generally agree that his prediction about ML/AI should be considered less-than-informed.
