Software dev with 20+ years' experience here - My primary keyboards are all 60-65%, i.e. without the function keys. I use a ton of keyboard shortcuts in my flow. I rarely use the function keys, but when I do, I get to them via layers.*useless for you
Most power users ie. programmers use function row keys all the time. Replacing it with a touchbar was a massive pain in the **s.
But I do agree with you on the second point (**s). As a touch-typist, I can't afford to look down on my keyboard for input. The Touch Bar will have significantly slowed me down.
