The printing press eventually won...however thanks to the other invention which really changed the power landscape - gun powder.Free communication has always been a thorn in the side of authoritarian governments.

For real change, It will probably require invention of very powerful energy source usable by individuals/small groups - think force shield, energy weapons, AI defenses sensors and/or galactic engine...for escape :]
