IC vacuum tubes.
This may well be kinda peripheral to the subject of Arms-D (Please!
No comments about THIS issue on the list!), but it seems to me that IC
vacuum tubes don't have much use.  At such high voltages, the
conductor spacing in the chips makes for a pretty sparse layout.
Denser than conventional tubes, to be sure, but still pretty
space-hogging.

After all, the same thing is the reason why modern IC's run at low
voltages, especially internally...  to decrease the amount of
dialectric insulation necessary.  With a given dielectric (silicon or
something like it), lower voltages mean smaller interconductor
spacing.

However...
