Depending on what you're working on you might need a pretty beefy machine, but nobody really wants to deal with the actual hassle of managing a fleet of high powered machines.

This feels like another solution a lot like Stadia. There have been countless other attempts at the same idea, but the problem is always the same. Latency and user interaction between the local and remote hosts always end up being overwhelming constraints.
