I think they realized that too late. It’s a shame though. In a MacBook-only world, I wonder what would have become of it.
Many of times I slipped off the delete key and hit F11 to zoom the window.
I don't know if that would have worked as individual buttons.
We went from Touch Bar + T2 to Apple Silicon pretty quick. The Touch Bar was the user-facing toy to drive adoption, then they just dropped the bar and kept T2 as they built out more functions in it being taken over from Intel hardware.

It's like how the iPhone Air is just a test device for the iPhone Ultra's hardware capabilities and the 16e was a device to test the C1 modem. Apple's short lived "experimental production" products.
It removed the physical function keys, which is a huge no-no overall. The initial version also lacked a physical Esc key.
But the bigger issue was the notion that it was created in spite of having a conventional touchscreen on the laptop instead. Apple has been rather weird, petty, and immature about putting touch on Macs, stemming from Jobs' ill-conceived "your arm gets tired if you have touch on a laptop, boo hoo" speech which has never been correct and continues to be misconstrued as scientific when it isn't.
Luckily, the market soundly rejected the Touch Bar and Apple is now due to release Macs with proper touch on them. It took a while, but this era of pretentiousness is over.
In my own applications I often put common functions on the touch bar and I like the convenience of it in that way.
I think most people simply don't use the F-keys much so it's not usually that big of a problem.
I'll believe this one when I see it. "The Year of the Touchscreen Mac" has been confidently predicted for almost as long as "The Year of the Linux Desktop."
I don't think native haptic support would have been enough to save the Touchbar, but like the author I'm a little surprised that Apple didn't even try it.
I'm pretty much convinced they knew it was doomed before it was even released.
It was made worse since desktop keyboards lacked the feature so you couldn't practice/learn the UI on anything but MacBooks. Keyboard shortcuts were far more useful since they worked on any Mac and whether or not you were using an external keyboard.
That lack of external keyboard support also meant developers couldn't write decent interfaces for the TouchBar unless they had the right MacBook. The simulator was not sufficient to actually test real world usage for positioning/ergonomics.
I found it to be a top to bottom failure of a feature. Small OLED screens on physical buttons would have been far superior ergonomically. Using the space for better cooling on the i7 and i9s would have been a much much better use of that space.
