Regardless of my opinion of the Touch Bar, I would hardly call the Lenovo Adaptive Keyboard row the invention of the Touch Bar. They are essentially just a row of non-physical fixed buttons with changing inscriptions. As far as I know there is no way to customize these buttons or anything because they were baked into the hardware and therefore there is only a very limited amount of inscriptions that are even possible, and all of those in a single color. No user customizability, no way to change the position, or width or size of the buttons. No functionality for scrolling or swiping left and right either. No way to display actual content there like video/audio scrubbers, miniature timelines, etc.
The big thing about the Touch Bar is that it's a full multitouch Retina OLED screen that can display literally anything that fits on there. If it's actually useful for a workflow or not is another discussion, but the Lenovo screen has essentially none of the good ideas behind the Touch Bar (except maybe for the inscriptions changing based on application, but even that seems like a stretch since apps can choose to have whatever they want on the Touch Bar, not just select one of a handful preselected button rows). They are basically function keys made non-physical with a (by the hardware) limited amount of key inscriptions.
