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.
