I agree that one doesn't necessarily need a fast language, but I think that the "hardware is cheap" idea is very misleading. Renting/owning 5x as much servers may be cheap, but maintaining them isn't.

check out https://cloud.google.com/run. I've never had issues 5x-ing compute on it.

All the other services that compute hits (e.g. Postgres) are a different story, but that doesn't really matter when picking a language.
