I hope I didn't get permanent damage but I hurt myself badly with it. I was trying to put the volume up a bit while wearing earplugs (it was very low) so I pressed the "up" volume key. I accidentally pressed few pixels to the left from where I should have pressed and it went to FULL VOLUME without a warning, blasting audio and hurting myself badly.

This could not have happened without the touchbar. This is horrible UX and I will never trust that (work) computer again.
