Crypto algorithms have a lifetime, and consensus is no different.

Is it likely to be more than a few years?  Yes.

Is likely to be less than a few hundred years.  Yes.

Every algorithm involves trade offs and it's the job of a thoughtful dev
team to examine those trade offs and come to a consensus optimal solution.

This field is only 9 years old, and there is a large amount of R & D in
this area.  So we can evaluate what seems to working better and what seems
to be working worse, transfer that to BIPs, create code, test it, try to
achieve consensus.  The normal path that has served free software projects
well.
