> apparently my keyboard posture is terrible and I float fingers up their periodically

Same. The short time I was exposed to the touchbar it felt like I was constantly being berated for my keyboard posture. Apparently the "at rest" position of my left hand leaves my middle/ring fingers hovering over the escape key (I had the earlier model that didn't have a physical escape key).

Not to mention losing access to the physical f-keys decimated my custom hotkey usage for certain software.
