Yeah, it definitely seems like the "big deal" bugs are confined to last-gen consoles; however, the online reaction would make you think it's the game as a whole.

I'm ~30 hours into the PC version (on Stadia) and the only bugs I've seen have been things like food/drinks floating in the air when you knock tables away. Nothing game-breaking, no matter how hard I try to break it.

It is a big deal because both the PS5 and XSX are at risk of going into a death spiral right now. Because most people have only been able to buy units at double the normal price via scalpers, people have been buying way less games than normal. Which means that if this continues, developers just won't make games for these consoles and people won't buy them. The enormous failure of Cyberpunk is only further increasing this risk, by preventing people from spending money on actual finished games.
