I'm not sure why someone hasn't developed a company offering services that distributes AI across all idle or under-utilized VM's and PC's for enterprises in order to serve open sourced models. Outside of the electricity bill, there's no additional expenditure and you get the AI.

We've all seen the office spaces where there's 200 empty computers on a floor. Combined, it's something like 500 cores at ~3 Ghz each and around 3 TB of RAM. The networking is already there and software like exo already exists.
