Will there be any more bugs to find after AI has fixed them all?

The number of possible programs is infinite. The number of possible bugs is uncountably infinite.

Every fix is another change and every change is another chance to break something

We, as a society, haven't used "AI" long enough to say this. I mean, "AI" is the worst it will ever be right now, and it has almost infinite short term memory, no 5+-2 working memor, and no cognitive biases.
