I like the Touch Bar. I use it all the time contextually in whatever app I am using. For regular, non-tech users, I've noticed that they use it too. It allows those folks to quickly access options that were previously keyboard shortcuts.
As an aside, I also enjoy the quick access to emojis.
I'm really not a fan, but recently I noticed that WebStorm (IntelliJ) supports it and when looking down to find the F7 key (find all references), I was pleasantly surprised to see the option right there on the TouchBar.
Now, if I could figure out how to customize which options appeared on it, that would be great.
I think the biggest problem with it was
1) Replaced existing keys that people used
2) No apps had been updated to use it
Now that more apps use it, I can start to see some benefit from it.
