In a hypothetical distant future where private keys are getting closer for the strongest supercomputers to guess, are there any potential BIP opportunities that could increase the security of all private keys in the network? Including lost/old ones, like Satoshi's for example?

I know it's ridiculously unlikely to ever be a problem (I've personally done the math) but I'm just curious if something like this is possible if it becomes an issue 500 years into the future of bitcoin.

I read about this but can't remember where... it was in the context of quantum computers. Basically there are ways to create quantum-resistant private keys that work with the bitcoin protocol. You would have to sweep your funds to a new key. I don't think we can strengthen existing keys if they become vulnerable. Inconvenient, but not fatal to the timechain.

Strengthening existing keys is exactly the problem I'm curious of it CAN be solved.

The "finding Satoshi's wallet" problem is what I'm curious if can be prevented if the need arises in the very distant future.
