Are cryptonote coins the future?

First off, I want to congratulate Bitcoin on the 40% rise this past week. I'm not here to spread fud, but rather discuss the outlook of our sphere.

I hear a lot about fungibility and the worry that's created from so many exchanges being hacked/exit scamming in the past (and most definite future) and the impact this has on Bitcoin, or any public ledger coin rather. Could it be possible that crypto transitions to a coin that keeps its scarcity and mining algorithms similar to Bitcoin, but advancing the privacy of what crypto is meant to be? I just don't see how every bitcoin can be 'clean' and rather some being traced back to a malicious event.
