Adaptive keyboards are actually more oriented towards beginners than advanced users. They optimize for feature discoverability (and coolness factor).
Physical keyboard is current optimum for text entry precisely because it is not adaptable, and that enables you to adapt to it. Without muscle memory you are much, much slower. When an advanced user wants to refresh page, they can instantly recall Ctrl+R combo and just press it, without glancing down and coordinating between hand and eye to tap the icon, and then verifying the tap was registered. With adaptable keyboards the advanced users lose all their edge.
That said, swiping is really nice way to enter English text on touchscreens. I still hate switching to numbers and special characters, or entering non-dictionary words, but it works unexpectedly good. I agree with you that more innovation is needed.

Interesting example, I can imagine something like an Ctrl+R combo to be a bit cumbersome on a software keyboard, would need to test it to be sure though.
