Does Ethereum have any serious competition? Is there a token/network that could replace Ethereum one day?

Hi. I'm wondering if there is any serious competition to Ethereum, especially after Ethereum has upgraded to Ethereum 2.0 and proof of stake. From my understanding, Ethereum right now is the king of Dapps and has a nice, and growing ecosystem. With proof of stake implemented last year, transactions are faster as well.

I was reading some posts in Reddit from the Ethereum subreddits where the consensus is that it's very hard for the competition to push over Ethereum now. But those are Ethereum subreddits so I think the comments are biased.

Does Ethereum have any serious competition? Or is the competition so far behind Ethereum, that it's unlikely that the competition will gain any real traction to replace Ethereum?
