>Even Ethereum abandoned the idea of completely switching away from proof-of-work because they realized PoS isn't completely workable

No it didn't. I follow Ethereum development closely and I know for a fact that's absolutely untrue. I'm not sure why you're misleading people about this.

You are right, I should have said "temporarily" not "completely". They abandoned the idea of switching to 100% PoS right away, and instead are trying to work on a hybrid PoS/PoW.

I think they didn't abandon the idea, but until they have a working prototype it's just a idea. Nobody is sure if it's possible to use in the real word, were many people will try to steal a few million dollars if they can.
