It’s certainly partially that, but that’s not the whole picture. Before, every old thing “everyone” knew how to do was replaced with a new thing “everyone” knew how to do. But at the moment, is there a new thing? I can’t think of one. All but the most niche products are built to be as easy to use as possible, and if it breaks or slows down, replacement is more preferred than tinkering. I don’t see the same need anywhere to get our hands dirty that leads to widespread proficiency like the image is talking about.
