I am not sure that Ethereum will die, but current tokens are running to newer more cost friendly platforms like Cardano, Hive, etc. I would love to buy in to some of the tokens but gas has effectively priced me out. I am limited in resources so I can either use my full monthly investment on a project or projects that interest me or I can cut my investment down to 1/3 so I can use the other 2/3 on gas fees. And with that being the choice with ERC20 tokens, I choose to give my full investment to non-eth based projects rather than paying off a miner's asics.
