Not really. A lot of people in their 20s might have never actually done much with a computer, yet they cannot put their phone down. I know lots of 20-somethings that cannot type. I know even more that do not own a traditional "computer". It has nothing to do with fear, but lack of need.
I know people who are in their 20s and 30s who seem to be uncomfortable with computers, cloud technology, and especially AI.
In some ways I'm one of them. I will never let an always listening AI helper be in my home. And I'm <40.
