The Ethereum 2.0 project will never succeed because its main goal is to speed up transactions using the Ethereum network, but in reality, transactions on the Ethereum network are still very high, and if you want to speed them up, you have to increase transaction costs. So I can conclude that Ethereum 2.0 will fail because there will still be many transactions created in the future when many people use the Ethereum network.
I don't think Ethereum developers haa that solution, the Architectural design of Ethereum can only work efficiently in this manner, if really there was a way they would have done it, right from 2021 it will be implemented and done, there has been so many proposal on how to reduce the fees but it was rejected because there will not be a little decentralization left if speed is been priorities, I think the chain will remain like this just the way Bitcoin has also remain.
Sometimes, I'm flabbergasted how people still used the chains that suck up all their fees, people pay hug fees just to make their transaction quick on ethereum but the smart ones used layer 2 to curb this fees from feeding the Validators with all their incomes.
