I don't think it will, after all there is new projects coming up to the surface everyday and they all offer many good things like ronin that is used by nft, why it was used by axie infinity because eth is not suitable for newer projects like games with nft which require fast transaction speed, eth is not suitable for many newer things like games, maybe if they decide to make eth faster and cheaper it could live longer but it seems eth is also slow in update.
that's why development will continue. the ethereum team should be able to figure out the market that has mostly moved to other networks. looks like this year ethereum is really getting hit by a new network.
they can only provide long-term updates that are being done. although still in delay, I hope as you say. ethereum could give better hope for the future of crypto trading.
