A recent Wall Street Journal report delves into Gen Z's surprising lack of keyboard typing skills, featuring interviews with several individuals and revealing some startling statistics.
People who know nothing more than how to operate a smartphone are not tech savvy. They can't even do that properly. Never seen anyone from that generation use an ad blocker or revanced or anything else that combats enshittification.
The second highest age range is 25-34, and the third highest is 12-17, which is also included in Gen Z.
That said, I would argue that, while knowing how to use a smartphone doesn't make you tech savvy, knowing how to use an ad blocker doesn't either. It's as easy as installing an extension.
