Computers themselves are still pretty fixable.

You are rare and these stereotypes are mostly false. Most people in every generation can’t fix a computer. Maybe the only slight echo of truth is that during the millennial childhood and youth, at least in terms of raw numbers, home computers peaked as the main “tech” children were exposed to, so there might be a little more people who are not professionals, but have some extra comfort with them. Still, that’s a stretch.
