The interesting phrase here is "scalable fabrication". Like the many new battery technologies, there are many ways you can make next-gen transistors, but none of them yet has been manufacturable at large scale. To me, it's not the transistor that's impressive in modern technology it's the manufacturing process we use to make large scale silicon devices. It's those that are becoming increasingly hard to advance and those that we need to find replacements for.
