I think pros should be able to embrace new things. I use emacs and vim for about 70% of what I do and I never use the fn keys. ESC is remapped to caps as well so I'd have preferred a macro key or something instead that I can customise as I please (there is probably some software for that out on the net somewhere anyway but I like native stuff) like define app/global specific keystroke patterns (e.g. you define it as cmd-s so you can use it to save or something) .

The touchbar for sure is lacking something, not sure what though. I agree with apple that the fn row could be utilised better so I applaud them for trying something, not sure if the touchbar is the right way though but should apple stick with it and keep going in the right direction again I will for sure customise the hell out of the touchbar.
