I'll push back a bit.
As long as there is a value proposition for ETH it will exist. Obviously there are some red flags around it but at this point it has been around long enough and has "decentralized" enough that it likely won't come crashing down.
The issue with it right now is state capture and that has been exacerbated with their currently crappy staking mechanism. ETH is far from being a complete product and will still take many years to develop.
Now ETH trying to brand itself as ultrasound money (which I don't think Vitalik is trying to do) is just plain dumb as you don't know what the supply will be even one block from now.
Centralization is still a big issue with ETH but right now I see it could still play an important role going forward as the permissioned censorship blockchain that businesses and governments like and would potentially use. Comparing that to Bitcoin is stupid and they will fulfil different purposes in the future.
This is just my opinion though.
