Considering that Gen Z is usually defined as being born between the mid-late 1990s and early 2010s, I wouldn’t support the first half of that statement. Everyone born in the first half of 2005 or earlier are 18, making them adults, so about half of Gen Z is adults.
Now whether this article uses that age range properly or whether it’s just someone using the term to mean “young people”, I have no idea.
But the premise of the article that just because someone uses technology all day makes them somehow invulnerable to scams (something that has absolutely nothing to do with how much someone uses tech) was ludicrous from the start.
Really depends on the game. I usually get a lot faster and more precise adjustments using KBM, so I prefer that for games like shooters and anything where precise 3d movement or fast reactions is an issue.
Basically the only games I play with controller are the ones that are really well optimised for controller and kind of meh for KBM and the ones on my Switch.
