About 15-20 years ago companies started experimenting with the idea that every key on a keyboard could be a programmable screen. That way you could ship one keyboard for all languages and every app could display shortcuts on the keyboard. Sounds awesome.
The problem was that users type on keyboards all day long and that eventually causes these little programmable touch screens to damage and fail.
Keys still had to be mechanical because a full size keyboard with no moving parts is very tiring to type on and we need physical feedback to be able to touch type without many errors. Typing on a computer is very different behaviour from typing on a phone or tablet.
The Touchbar was conceived to address that problem by just having one touch screen strip for programmable shortcuts. As we have seen that was still an issue when the component fails.
It wasn't widely used anyway because using regular keyboard shortcuts is quicker thanks to the Command/ctrl key and muscle memory.
So it was better to get rid of it completely.
