The new generation has largely switched to exclusively using thier phones. I figure this will have some pretty negative consequences for computing, but was also inevitable given the state of things
People in the new generation who use computers to do real work don't use phones because you can't do very much in the way of real work on a phone. Developers also don't use phones because you can't develop (much) on a phone. They are pretty much pure consumption devices.
What's happened is that the phone has replaced the PC for casual consumer-level computer use, except maybe high-end gaming.
