Learn keyboard shortcuts, and no one needs a touch bar.
The touch bar works best for things accessed sufficiently infrequently that muscle memory won't be a thing.
I think the touchbar is a cool idea and I loved that Apple explored it innovated. But I also think that ultimately it's not a good idea and good design. Particularly for the power users.
Then again, I hardly ever use the touchbar either.
I tried to give this a good go. I remembered when I was the young kid thinking about all those old fogies who could not adapt to changing technologies, and now, I am the one yelling "get off the lawn!"
I can find out, sure, but my experience tells me I won’t, so for me the Touch bar is a win, simply from a discoverability standpoint.
