I dont think ethereum would die. It's an essential tool for most projects to create their very own tokens. They are used to create decentralized businesses which are not in existence before. Though the fees are insane, this wont stop traders/investors from using Ethereum's platform because there is no other tool that can provide the same services. Proof? You can see it for yourself in this forum. Majority of projects are ERC-20 tokens which is the technical standard used for all smart contracts on the Ethereum blockchain for token implementation.
