Last night I couldn't sleep and started questioning current tech and its future. Is there no more sustainable way?

Do we really want giant concrete buildings sinking megawatts of electricity and millions of gallons of water? For what? Displacing jobs and disrupting society?

I believe AI can be good. But not at that cost.

So what if it was running on mushrooms? (Not hallucinating — actually running on mycelium.)

This is a research compilation. The shiitake memristor paper is real (PLOS ONE, Oct 2025). DARPA is funding mycelium computing chips. Adamatzky's lab has been publishing in Nature Scientific Reports since 2021. A mushroom field produces food, creates jobs, sequesters carbon — and might compute.

I don't know if this is the answer. But I think it's a question worth asking.

It turns out, we're not that far (but not that close either). Claude burnt a small forest worth of compute to help me compile what could be done about it.

They will be soon, when "AI" runs on your laptop (some already does).

All that surplus electrical power will warm and cool our homes, and giant concrete buildings will provide affordable housing, so badly needed.

If billionaires can profit from bubbles, so can we working and retired slobs.
