I taught a bunch of Gen Zers back when they were in high school. None of them knew how to type well, and it was a rarity that any of them knew how to type at all. I was supposed to teach them things like Microsoft Office, but we had to start with typing and basic PC usage before we could move on to something as complicated as MS Word.
This is what happens when people don’t use computers and instead just use cell phones.
Shortly after I returned to the States from Fukushima (a little bit after the disaster), I was taking an emergency response course on radioactivity. Everybody there got to use a Geiger counter on themselves and their belongings and various things in the room. The only thing that set it off was the purse I had brought back with me.
Anecdotal, obviously, and it wasn’t highly radioactive, but I did get rid of the purse.
