There are many quantum resistant encryption algorithms - https://en.wikipedia.org/wiki/Post-quantum_cryptography#Algorithms

As for quantum computers, there is some debate, but a number of companies have “quantum computers” but it’s arguable if they work correctly and they have limited Q-bits meaning they can’t do anything of significance yet.

This isn’t the first game to do this, this has been happening for a while. Switch had a number of games where you only got a digital download code and PC games were doing that for years before they stopped having physical releases.

There was some recent reports estimating 2028 or even 2029, probably because you can’t make a device better than the ps5 at current prices.

Either new technology needs to come along or prices need to drop and that’s not likely for the next year or two.
