Re: Would we have got to the moon with no semiconductors?
I'd forgotten about that Korg nutube device, but that's still not what I'm envisioning 21st Century valves to be.
The nutube is still a glass bubble with wires, uses a heat source, and is specifically aimed at audio applications.
I'm thinking more of a digital device, that's what is needed for computing.
What is smallest a 'valve' could be made ?. Is there a limit on how close elements can be ?.
With micromechanics and nanotechnology I'm fairly certain a 'valve' computer comparable to what Apollo used could be built, if the will was there to do it.
Cheers,
