I know your answer's a bit of tongue in cheek, but Apple has already explored this concept through the Touch Bar.
Why did the Touch Bar fail?
Because a notebook has two surfaces. Users are forced to constantly shift focus between the screen and check the keyboard. The whole point of a keyboard is you don't have to look at it.
With a smartphone, there's only one surface and you're always looking at it anyway. Making it "active" (i.e., a touchscreen) costs nothing extra.
If you look at all the attempts so far, including Lenovo X1 Fold, Asus Zenbook Duo/Fold, HP Spectre Fold, and Huawei MateBook Fold, they all come with separate physical keyboard. It's because users want that tactile feel of the ridges and resistance. That's what enables no-look touch typing.
