We cannot expect that the number of users on the Ethereum network will decrease, although those who have chosen alternative blockchains for themselves have been waiting for this for a long time. But the project team is quite capable of solving the bandwidth problem, but so far we have not seen this in numerous forks.
that means ethereum is still in great demand by everyone, even though gas costs are so high for now, the project team is quite capable of solving every problem that exists, but it looks like this problem can't be solved in the near future, and I also analyzed what you said, not yet looking at the many branches they have developed during my time following crypto in the last few years, many flaws could not provide a solution for them to solve and it continues to grow to this day.
