I don’t think they are as stupid as you think them.
I mean, back when I was younger I learned pretty much all I know about IT by admining my own computer, and I pretty much did it by trial and error yes. However nowadays kids talk to each other over popular chat applications, eventually one tells another “hey just install this browser/vpn” the same way they install mods for their videogames.
Tho in the end I don’t think they will become techy savy tho, I guess just that tor and VPNs will become commonplace in UK.
Meanwhile the old boomers are the ones who are going to forced to shrug “just how it is”.
