Ethereum is the future after Bitcoin as I think. I don't think Ethereum will die. Ethereum is like the right hand of cryptocurrency. So don't give up hope mate
You are right, ethereum had already establish his position and I don't think that some other coins will be able to take its place, even binance or polkadot showing some potential in todays innovations, but as the other coins making some progress so is ethereum,cand hopefully we get to see some changes when the ethereum 2.0 mainnet launches
