The prime issue is lack of tactile feedback. I wrote quite a bit about this in a previous comment, in that we "touch type" because we get feedback from our fingers. Implementing a "keyboard" interface that requires a change of visual focus is not a good UI practice.
In your comment 25 days ago, you stated that the problem is the layout of the Touch Bar changes regularly, therefore you need to look at it. But this doesn't make sense for the Esc key, because the Esc key is always in the same place on the Touch Bar (and is always available while you're typing).
To me there are a couple problems. One is the changing layout as I mentioned and the fact you have to shift focus constantly because you can't feel where things are (esp since they change from app to app). Then secondly the lack of feedback. I wouldn't mind the touch-bar so much if it hadn't replaced keys that some people use constantly. As an add on above the keyboard, sure... while I wouldn't be crazy about it it could be handy for some people. But half the comments talk about how you can re-map keys to work around it... and that to me spells UI downgrade. A fair percentage of people are perceiving this as enough of a loss in functionality they are finding work arounds.
