Could an abstraction of "single Linux computer" be actually useful with Earth-scale latencies?
Think of it in a "Compute at home", "folding at home", blockchain-sense then latency doesn't matter as much, I do not know if anyone has tried solving things with big clusters separated by 40ms-60ms latencies.
Know those moments in movies where they put “all the computers in the world” onto the task of cracking some encryption before it’s too late? This could be used for the technical part of that (once you’ve got all the HPC labs’ cooperation.)
