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.
Well good luck for anyone staying in POW and finding developers for the old expensive chain while all the brainiacs are moving to POS because that's where the future is. The whole POW ideology is just pointless after POS. And POW will mostly be pushed by unemployed miners with rigs they can't use anymore.
