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 don't really think that the ETH-team has really much of a choice here. Yes they could decide to keep on using the PoW consensus mechanism in order to keep the big mining companies happy but i think the negative reputation that they would get from the majority of the people and the press would just be too much. In the end the last few years have all been about energy efficiency and to develop environmentally friendly alternatives for transportation, heating, electricity and so on. So it is really hard to tell to people that all those crypto miners use up more electricity than a whole country needs to function. I just read about a research that said that BTC miners use up more electricity than the country of Ukraine, that research is from 2019 so obviously before the Ukraine war.
