So Bitcoin is thought to maybe go PoS after Ethereum can prove the 'worthwhileness' of it's PoS network. Once PoS is fully implemented, does anyone foresee what will happen to all of us miners?

It's possible I don't understand things well enough about PoS. But from the many writings I've found, specifically of Ethereum's PoS implementation, is that mining will become obsolete. Doesn't that mean we're out of the picture?

Sounds like an awful idea. Who honestly cares that it takes X amount of power to run the network? Just my personal opinion there- but the real question here is if we are going to even exist in another couple years? If so, I imagine it will be mining some other altcoin.
