Because we need advances in material sciences, optics etc to build anything new.
Devices will stay the same until we invent new technologies.
We've certainly progressed semiconductors a lot, but it's still just the same old process for the most part. I think it's areas other than semiconductors that will drive innovation, new optics/displays (foldable, holographic, wide fov ar on a contact), solid state batteries, etc.
Would sure be nice to have properly 3d semiconductors tho. As many transistors as there are across x and y, there should be across z too.
