Or maybe the AI is sufficient to act as a filter, but insufficient to surpass it itself. It stagnates.
After all, an AI that can destroy a civilization isn't necessarily "intelligent" in the same way humans are. Or even capable of self-improvement. It could be sophisticated enough to (accidentally?) destroy its creators, but no more than that, and without evolutionary pressure, it may let itself die.
