I don’t think the touchbar particularly effects developers. The ESC button is still there when in an environment (terminal/text editor) that needs it. and frankly, even that really only applies to VIM users. I get your post is about other things than the ESC button, but I have run into a lot of people who think that is true and your click bait title doesn’t help inform people.
Bigger issues are about the hardware internally and the ports and battery. Why did they not include just 1 standard USB and ideally an HDMI. And why couldn’t they have kept same thickness as before and had a massive battery life. Tsk tsk tsk.
