Apple Researching Keyboards With Adaptive Displays on Each Key

What do you guys think about this?

I suppose it would mean they manufacture one keyboard (hardware) and then use the software to localise it. Beyond that, there may well more innovative ideas appearing and Apple will feature those ideas, but the whole thing probably driven by drive to simplify manufacturing.

This is very like the Art Lebedev keyboards. I would wonder about the utility compared with the extra price of parts and battery usage, but I would rather have this than the Touch Bar.
