This isn't a space I know too much about, but even if we all start using quantum-safe encryption for everything today, won't the arrival of quantum computers that can break traditional encryption not still be a big deal?

Given that intelligence agencies, tech companies and various bad actors have been storing encrypted data for a long time, hoping to decrypt when (if?) that day comes?

Definitely, but then the damage is limited to the encrypted data that those actors managed to intercept some years before. Compared to QC arriving to an unprepared world, that's a very limited impact.
