OK, well you haven't given a lot of context. If he's close to a hundred then it is more understandable why he has never used the internet.
If he's as I'd expect, based on your 50 year fact, under 60, then its hard to see how a plater might find work without the internet. I suppose he may have worked for the same company the whole time, but he's still missing out on Netflix/Amazon Prime and what not, and in a lot of ways making things a lot harder for himself, assuming he has to visit a bank every time he wants to transfer some money. All I'm saying is its hard to see how someone of that age could function very well without the internet. I never claimed to be intelligent btw

Yes we're 'over-reliant' on our phones, but people used to say it about TV, and radio, and telephones before that. I wouldn't necessarily say we're 'over-reliant' on the internet though, its almost as essential as electricity, gas and running water nowadays. In fact, I'll be getting shot of gas before the internet.
