The way I've seen discussed is a move to something that is resistant to whatever advances arise (quantum resistant, whatever), with a (very) long grace period before funds secured with old keys become unspendable in a fork.

Interesting. Do you think that "thing" could potentially be a fork of bitcoin that gives each private key an additional layer of entropy?
For example, to "find" my wallet with funds on it, I would essentially have to put in a great deal of computing power.
Idk if something like this is even possible.
Nah I think it would just be moving to a new scheme entirely with a decently long period where both are supported for people to move funds over.
