In technology none of what you're talking about matters.
Users do not care who does it first, they care about who does it the best and most efficient. The majority of people who are deeply into this stuff see what's going on and are pivoting accordingly. I'm not saying ETH is dead, the network and money locked in it is far too grand for it to go away. With that being said, you're going to be paying way more in fees just doing anything on the network than on anywhere else.
This may not matter for noobs who don't know shyt about DEXs or how to utilize other blockchains. But for people who do, why give away gas fees that can be invested elsewhere?
Some of the BIGGEST ETH projects right now are starting to venture out and are either exploring other chains to build on or already started doing it.
I've seen this with MANA, one of the founders literally is working on a completely different game/world (Big Time) that isn't even on ETH... Why is that? Because they are realizing that there is no easy fix/solution for the congestion and it's only going to get worse from here.
Another example is ENJIN building a completely new platform for NFTs called Efinity. The information and data out there will tell you that people don't care about nothing you're talking about breh.
Mufukkas used stan HP's Palm phone with WebOS until Apple and Android came through and crushed the fukking buildings.
This is tech we talking about here. If you're offering a service/product that is less efficient, slower and expensive than the comp people will rotate.
