I don't believe it will happen, Eth expensive transaction fees will remain a burden for its remaining users soon it will be felt by the network because many Ethereum users/developers are already leaving the network that's why I believe that there is no change will happen on Ethereum even if the Full implementation of Eth 2.0 will be finish.
Any source for that? I think we arenr sure how eth 2.0 will work out but we should wait and see what could be the possible outcome when its already happened. I dont think judging too early is gonna help the problem. Scaling isnt an easy task. Maybe other chain could sound it very easy but that is because their users arent the same in number on eth. We all knew that many has been using eth network and that is a fact survive by them. Anyway Im excited when eth 2.0 really come soon.
