327h, and I haven't seen a single AI rebellion. Unbidden/Swarm, no problem. Even when using materialist with synth everywhere. I tend to play "nice", so my robots are not terribly unhappy, but the event is supposed to trigger based on a galactic sized check, and not just the player.
I had the rogue synth chain a lot of time, but I always ended with the swarm or the unbidden.
