Apple looked extensively at touch input. They made many public statement that their research showed that a touch screen was a different use case from a MacBook Pro entirely and were not moved to include a touch screen on the MacBook Pro (despite Microsoft introducing such a device).
They introduced the touchbar as a compromise, suggesting it brought some touch controls to many Apps where they could be most effective.
But they continued to engineer the iPad, and refined it into a formidable touch input device, and added Apple Pencil features as well. They also came up with Sidecar, where the iPad could be an additional output (and input) device for your MacBook Pro or other Mac.
The war is over. The touchbar was not able to earn its place above the keyboard. Unless you buy a refurbished model quickly, the touchbar is gone.
The winner of the touch input wars is the vastly superior touch input device you can connect alongside your Mac, the iPad. And if you like, you can even add Apple Pencil to full-sized iPads that support it.
