Swarm compute should be the norm for all compute - so much unused cpu across all the devices we collectively own.
That is unless Tesla is already using their idle cars as remote datacenters, crunching numbers to get better at self-driving.
For example, if I have a few servers, laptop (connected to power) as well as a desktop PC and they’re all connected to a fast local network, it’d be great to distribute the task of rendering a video or working with archive files across all of them.
I haven’t tried it, and not the norm, but I agree it should be more common. We have a global supercomputer with higher latency, but still a supercomputer.
