It’s really down to education. My six year old son owns a Raspberry Pi 400, he’s growing up with Linux and he definitely knows his way around files and folders.
The problem is that people don’t own (real) computers anymore. A chromebook is not a real computer, neither is a smartphone.
Thing is, it’s not that much different from when I was young. When I was at primary school, teachers used to collect me from the classroom because they had a problem with their computer. I always wondered why everyone thought it was so difficult, but later on I realized that I’m the exception.
I think 95% of the people just aren’t interested in computers and by throwing smartphones, tablets, chromebooks and Windows 11 Simple Edition at them, they’ll never need to be interested in them.
