Other 'Professional' software such as video editing or music production usually sticks to key combos rather than F-keys. This is traditionally why the F-key row is used for things like brightness or volume, and why Macs use these as the default function.
computers have gotten easier and learning what F5 does is not in the realm of necessary things that people should have to know to operate their work device
If you are not memorizing the keys, then you will need to look down at the touchbar to figure out where to tap to do what you want to do.
If you need to be looking anyways, why is it better to look at the top of the keyboard, instead of the screen where your eyes are normally located?
Replicating a touchbar style strip on the screen is a much better option than anything on the touchbar.
That's actually pretty sad (and should be remedied with some education, starting with emphasizing the fact that tools have a learning curve and you're supposed to follow it). I mean, look at non-professionals working with computers daily, like e.g. shop clerks. They have every possible shortcut used in their sales/inventory management software in muscle memory.
Not only do people not know what the F-keys do, but they have no ability to determine what an F-key might do in any given situation.
Not so with the touch bar. The touch bar will do what the touch bar indicates it will do, which is displayed on the touch bar itself.
