Crypto's greatest weakness has always been security. Even if the algorithms themselves hold, humans need to keep their keys safe. We have decades of experience now showing that humans can't do that.

I wouldn't be worrying about the algorithms so much as I'd worry about all of the end-users who are going to get their keys stolen and their wallets drained thanks to the deluge of new vulnerabilities in operating systems, browsers, wallets, personal agents and other software.
