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'm not sure what you are arguing here. Are you saying that POS isn't secure? POS can be just as secure as POW blockchains, even more so since there are no 51% attacks based on hashpower rented from places like nicehash. The added benefit of POS for retail investors is that they don't have to buy expensive computer hardware from china and mine with expensive electricity. Anybody can stake $Celo, $ICP, or $NEAR.
