This is one of those ideas I think makes perfect sense, but requires so much operational change for the entire stack, that it would be very difficult to scale:

- Convincing labs to run distributed, burst-y inference

- Convincing people to run their Mac all day, hoping to make a little profit

- Convincing users to trust a distributed network of un-trusted devices

I had a similar idea, pre-AI, just for compute in general. But solving even 1 of those 3 (swap AI lab for managed-compute-type-company, eg Supabase, Vercel) is nearly impossible.
