The Touch Bar is nice to have but not a necessity. I don’t think Apple will get rid of it, though. If they were, they likely wouldn’t have added it to the base 13” Pro.
They didn’t add it to the base 13” Pro, it’s always been available on that model for as long as the Touch Bar has existed. What they did do recently is discontinue the non-touchbar version of the 13” mbp.
None of the new machines that Apple have released since the 2016 debut of the touchbar have had one. It remains limited to just the current form factor of MacBook Pro.
None of the desktops got it, and the only other laptop — the air — didn’t get it.
Apple don’t seem to have a lot of enthusiasm for it, or confidence in it.
