I think that the Touch Bar exists only and one-hundred-percent because Apple doesn't want to hurt the iPad. It doesn't even theoretically offer improvements over an on-screen toolbar with touch capability.
That would be a radical departure for Apple. They're always cannibalizing their own product lines.
Apple is very open about why they don't think a touch screen makes sense for Mac. They absolutely could change direction but as many others have pointed out, the PC form factor is slowly dying, so why would they?
(I'm not even saying they should have one. I don't care either way. Just that the Touch Bar is not a good replacement.)
No because touchscreen makes zero sense for Apple.
OSX is simply unusable with a touchscreen. And we know this because you can remote desktop from an iPad and try it yourself. At some point when Apple has (a) built a unified iOS/OSX UIKit so developers are forced to auto scale their apps and (b) rewritten OSX to use it and (c) convinced enough developers to use it then it is a possibility. But that is years away.
I can very much see Apple bringing the iPad Pro's pencil to OSX however.
The Pencil would be the only thing they could do to a standard, no-Touch-Bar-thank-you-very-much MBP that would make me stay with Apple, because I digitally draw and paint a lot. I currently have a DisplayLink-driven USB3 display tablet with a stylus for exactly that reason (and, as with everything else on an iPad, an iPad doesn't begin to replace it because it can't run Photoshop). I'd love it if they went that route. I doubt they will, though, because--well, I think they care about the iPad way more than they do about the Mac.
Personally, I'm upset enough that they no longer have a matte-screen option. To take away the optical coating so it could be a touch screen might be sufficient to drive me to another laptop. I hate glare, and the trackpad works fine for me; I have no interest in a touch screen.
As another vim user, it's probably better to get in the habit of using Ctrl-[ or Ctrl-C (though Ctrl-C has caveats in certain situations).
