I was around 25, it took me a month or two but I didn't have any nausea issues. I was at the point where my eyes were getting super blurry at the end of the day.
8/10 maybe more, maybe less. Software developer, don't really have issues with tech, but put me in front of a quantum computer and I sure as shit would be lost, but fine with consumer products.
Idk, I'm sure some business or corporation will make a pretty penny out of it...
