It's still a wild logical leap to me that we went from this observation, that maybe the bottom half of users never learn how the software works, to the idea that we should build software that is actively learning-hostile. In the old era, we established consistent UI patterns: this kind of button does X, this kind of button behaves like Y, here are the tools to solve your problem. Maybe not everyone learned the patterns, but those that did became wildly productive. Now: who cares if buttons are recognizable as such, your bottom half of users tap all over the place anyway, so design for them exclusively. It's good to enable more people, but we also lost something in the process.
