If you want to make a claim that we won't even see change coming, maybe the large mammals->humanoids transition isn't the greatest example. That took several hundreds of thousands of years.

They did, to some extent, see it coming (in observing a threat becoming more prevalent and dangerous). But they did not have a way to stop humans. Meanwhile, I'm just staring at the power switch on my computer, wondering how we'd stop AI.

(This is not an argument for unrestrained AI - we should safeguard, absolutely. It is a counterpoint to your "we won't see it coming" argument)

You would have more weight behind your words if there was any sort of precedent for AI as it exists today being super intelligent, or that you could make a case for some method by which you could suddenly ramp out of control without our notice.

But as is, all you're doing is making theories, and there's not much of any precedent for any of them.

You've just provided evidence that humans are the most dangerous, not anything else on this planet.
