My opinion is that eth will get replaced by a new smart contract technology in the future.
Do you have any proof of this happening? Any specific projects in mind? Better leaders? Better team?
that's a gimmick only and dozens platform with their new smartcontract already released but they are only copy-pasting the same method that already used by ethereum. onething that they can follow it if they can't build a complex smartcontract platform like what already did by ethereum in the past. the guy above you is only speculating.
many project has been try to replace but no one has been successfully do , how come you will got interest from other developer if you can make your own ideas and just copying other ideas from ETH. replace in price is much more in reality than replacing it in smartcontract technology.
