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)
