I also do not see them dropping this title anytime soon, there are lots of projects that have come after them and tried to copy their system directly but they have still not been able to make them less functional.

Binance launching of their own blockchain is what I thought would be of threat to ethereum before, but I can see that such threat has already been eliminated and majority of users would prefer to build their project on ether smart contract that people are already used to, and the issue of wallet, they cannot change their contract and start asking people to transfer their coins from ether to theirs again.
