Nanotubes are immensely valuable to many industrial processes though? They’re just in their infancy and limited by the “rudimentary” and relatively slow methods we have available to producing large amounts of them. They’re barely been on the larger market for a little over a decade.
Semiconductor devices were invented in 1947, but it took them nearly 25 years to replace vacuum tubes as the primary transistor in the majority of electronics.
I meant how nanotubes were presented like they were going to change the world. There was even talk of being able to build a space elevator with them. Maybe once there’s a permanent Moon base they will be able to take advantage of the graphene, but as you point out it could be decades into the future.
Those things are still all possible, and carbon nanotubes have already changed the world with their applications on a macro scale.
The point I was making is more that they are still in their infancy as a technological innovation and product, and it might need years if not decades more to be widely adopted into widespread use and be world changing for individual people.
