Yeah! The car of tomorrow was supposed to fly, for a start.
Apparently the reason that they haven't 'taken off' is that they can't license them. Red tape and beaurocracy is the only thing preventing flying cars, not the fact that the technology doesn't work.

I actually agree with the red tape and bureaucracy on this one. A staggering number of people are frighteningly bad at driving in a straight line. I've prepared an artist's conception of what it would look like if your average drive-while-texting-and-putting-a-dvd-on-for-the-

You may laugh, but there were plans for thermionic "integrated circuits" back then. the plan was to use a single large heater and arrays of cathodes, grids and anodes hooked up inside the glass to minimise the number of external interconnects. Had semiconductors not been as easy to make then this might have become the standard.
Certainly thermionics are more than fast enough for basic tasks, so a "4 tube" notebook where one tube just handles serial program/data memory, another does serial processing, a third acts as the clock and obviously a CRT and its driver tube(s) with some of the CRT's blank space being used as a random access memory and the CRT driver being used as the system clock.
see -A
That wasnt what I meant to imply...
I was LOL'ing because I now of a start up company in the late 1990's that did develop integrated vacuum tubes, but couldnt make them practical I think there defunct or bought now, its amazing how hollow-state as evolved -Right, Grenedier?

Erm, plasma TVs, VFDs, and the Loewe Multi-Valve?
Back in the good old days, quite a lot of tubes were technically ICs. You got ones with two triodes, a triode and a pentode, or three diodes and a triode, all in the same envelope.
