Kind of. I think a giant pile of them hooked together with good networking would be :).

But also, you can rent a single slice of one for tens of seconds and then walk away. I personally probably do about 20-ish GPU hours a month while dabbling (and only because I’m lazy and have my GPUs attached while I’m working, even if it’s just debugging the Python bits). For a V100 that’s $50/month, which is in the noise compared to dealing with owning infrastructure (and would be even less if I’d get by with a T4).
