I have felt similar to you. Gesture based interfaces aren't discoverable and there's no mental model or coherence everyone is building on. But playing devils advocate, I remember in the 90s and early 2000s an older generation taking computer classes to do basic things for work. All of the thought and consistency just didn't click with them. They spent 8 hours at work, but didn't spend their nights/weekends poking at and discovering the system. But the classes gave enough instruction for them to be productive. Last night I was watching my 3 year old son playing with a keyboard (piano). It's battery powered, there's an on/off switch, and a volume slider. It "turns off" after a few minutes to save battery and you have to switch it off/on for it to work. He gets very confused and thinks its broken--sometimes it times out, if he fixes that the volume may be down, at some point the batteries will die. I was thinking about the interface for a grand piano. It's always on and there's a physical lid that closes when it "turns off." That interface makes much more sense to him. Sure, that interface is better and more discoverable, but it costs much more, loses flexibility, and isn't as portable. I'm not actually saying one is better than the other. It was just something I was thinking about.
