Did you watch him typing an email and clicking the 'auto-suggested' words that were showing up?

I do concede that there are some good uses for it though.

When your hands are on the keyboard are you looking down at them to see where you are typing? Now you are going to take your eyes off the screen and see if the touch bar has something useful for you. I would imagine you are going to keep using the same keyboard shortcuts that you have used for years.
