Right, I admit there are better ways to do it, but I don't think it's obviously true that goroutines specifically are either more compact or faster to switch between. The benefits might be imaginary. The Go runtime has a thread scheduler that kinda sucks actually (it scales badly as the number of runnable goroutines increases) and there are also ways of making native threads faster, like SwitchTo https://lkml.org/lkml/2020/7/22/1202

Have you tried to context switch between 100k native threads? Good luck with that, in the mean time Go has no problems doing that with 1m goroutines.
