I was assuming ETH was going to remain a PoW cryptocurrency due to the constant delays of the difficulty bomb. But I've seen Vitalik's insistence on PoS, so it should only be a matter of time before the network switches to the new consensus algorithm. As you've said before, PoS increases centralization of the Blockchain as it gives whales voting rights with their huge stack of coins. Mainly, big exchanges like Binance, Coinbase, and FTX will be able to control the ETH blockchain with their stake. This is bad because it leaves the "little guy" out of the system. Of course, there will be staking pools that will allow anyone with less than 32 ETH to earn coins over time. But that doesn't mean you will be able to participate in the network's consensus (only validators with 32 ETH will be able to do so).
I guess that you get what you pay for (high gas fees in exchange for decentralization/censorship-resistance). ETH 2.0 will have lower gas fees, but it won't be as decentralized as the original version. At least, we have Ethereum Classic. If Ethereum (ETH) fails, then Ethereum Classic (ETC) will be able to save the day. Just my opinion
