>3D touch just feels like random events are happening for no reason.
I completely disagree, random events is what you get "Between long press, tap, and drag"--3D Touch gives you a similar semblance of control over your smartphone that you'd expect from other HIDs like a mouse. Maybe it's an age thing though, I'm in my 20s, and haven't been able to get my parents to adopt 3D Touch features.
Another feature I use all the time is 3d touch on apps which have quick shortcuts.
Where I agree is that there is too much of a fine line drawn between long press, drag and 3d touch and it is far from easy to be able to activate the desired one 100% of the time.
3D touch is a the equivalent of "just add more buttons". Sure, people will use the buttons. Doesn't mean it was the best design.
But because Apple didn't standardize on it, it will hopefully never get wide adoption.
That said, I'd it does eventually seep into Apple's low end, that will just make it easier for the company that takes a usability-first approach to designing a mobile OS, when they come to eat Apple's lunch.
I think that's a huge opportunity for whoever builds up enough gumption to think a new mobile OS startup is worth trying.
