This keyboard with remappable OLED keys was released almost 10 years ago: https://store.artlebedev.com/electronics/optimus/#51709
The only part that's similar is the key faces can change. They're still physical keys that press individually. It's not multi touch, a key can't suddenly become a slider.
Also, if that is true, perhaps what's truly new is that its actually usable. That's pretty much Apple's thing - making things more usable/useful.
That could be a jet plane from Lockheed Martin or a Thinkpad...
The jury is still out on that one.
