I am not convinced. I remember reading that the tiny field-emission
vavles etched into a silicon chip (which, BTW, are smaller than the mean
free path of an electron in air at stmospheric pressure so they don't
need to be evacuated) are considerably more radiation hard than
conventional transistors on the same chip.
