Once the police and military do not need a single human to operate, the basis for democracy may be completely gone.

Consider past periods of history where only a small number of soldiers could dominate much larger number of armed citizens, and you will notice that most of them were ruled by the soldier class. (knights, samurai, post Marian Reform Rome).

Democracy is really something that shows up in history whenever armed citizens form stronger armies than such elite militaries.

And a fully automated military, controlled by 0-1 humans at the top, is the ultimate concentration of power. Imagine the political leader you despise the most (current or historical) with such power.
