Typically there's a personality in those videos. I see what you're saying, and given the continued existence of "time-savers" MTCs, I'd say you're right even if it's not quite the same.
Automatically adjusting sensitivity on the fly sounds awful...
Especially in a fps where there's different sensitivities for different actions.
Like, if you're driving a vehicle for a few minutes, when you get out and start aiming is it going to be the same as last time you aimed?
Hell, some games have specific settings for each character you can select. How will the controller know which character you're playing and what you want?
I absolutely would not want a controller that knows my every move because when I'm waiting, in a unskippable cutscene, loading screen, etcetera, I'll sometimes just quickly rotate both sticks up and down.
Last thing I want is for a first or second gen AI controller to suddenly decide in a boss fight that what I really want to do it flick the sticks up and down rapidly.
Well it solves the problem of workers being distracted with hopes and dreams. Now that ai can do all that pesky "artistic expression" there's no job available. Now you can stop worrying about "finding something better" and get on with making your shareholders more money!
I mean, it's because those are easier and less risk-prone. The things you probably want AI to be used for probably aren't going to be ready nearly as soon.
And other AIs are being tested on masses so they just seem like novelties or annoying at worst. It's just not at the point of having more serious applicable uses yet.
