I use it every day for work and every day it gets stuff wrong of the "that doesn't even exist" variety. Because I'm working on things that are complex + highly verifiable, I notice.

Sure, Joe Average who's using it to look smart in Reddit or HN arguments or to find out how to install a mod for their favorite game isn't gonna notice anymore, because it's much more plausible much more often than two years ago, but if you're asking it things that aren't trivially easy for you to verify, you have no way of telling how frequently it hallucinates.
