I think it's not only "low tech". The bigger issue I see, is that everything tries to be an Assistant. For example, the Oculus Quest, there's a on / off button fine, easy to understand. Except, it magically turns itself on if it assumes, you may use it, and turns itself off if not used anymore. Unfortunately that is often not correct, so you start counter acting, holding it carefully so the sensor does not react and double checking if it turned off or just on again, when switching it off. Congratulation, they made a simple on / off switch unintuitive. I see this pattern everywhere. It seems ux designers are trying to hard to be clever. Just give us a Tool, that does one thing and always acts the same. If it doesn't make sense, let the user learn from it's mistake.
