I fear for ETH future, almost all smart contract projects are using the PoS staking algorithm but only ETH PoW stands alone, this makes ETH different and one of a kind smart contract project, I think vitalik buterin will regret is decision after ETH goes PoS.
I'd support the decision to go POS. POW is going to be a controversial topic for crypto in the future and for a sustainable utility coin, it would be better to be environment friendly. POS are not any less secure than POW and with the whole team involved, it would maintain it's trust. The only thing bothering it is it's slow blockchain, I don't see it improving a lot even if they introduced shradding as the chain is already one of the heaviest.
