There are crypto functions that are not amenable to quick solutions with quantum computers, right? Is there any reason why we wouldn't start migrating to those functions today? It seems foolish to wait until technology matures and present-day crypto is completely invalidated before we react defensively. Is anyone working on this?

The NSA and NIST have already called for the beginning of what they call "post quantum crypto".
