Somewhere between 2000 and 2015 pretty much everyone had a computer, because you needed it for doing all the computer stuff. Nowadays you can do so much on a mobile device that there’s no urgent need to even own a proper computer any more unless you need to do something very specific.

Professionals and hobbyists will continue to need computers in the future, but Joe Average won’t. You can pay your bills using a phone and watch movies on a tablet. Joe doesn’t have a 3D printer, write ISO images on USB sticks, try to recover data from old hard disks, flash LineageOS on an old Android phone, or SSH into a raspberry pi. If he still has an old laptgop tucked away in a drawer, it’s probably been sitting there for years because he hasn’t really needed it for anything.
