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.
Why you are worrying for the trusted coin like Ethereum.The people who had invested their money in crypto like new altcoin,they have fear.Because some project will be closed after the pre sale was over.Since Ethereum was the base of the NFT,Ethereum will not be collapsed at any point.If you had some money and want to inverse in good coin,you can choose of Ethereum.
