>I bet you that for every bad history event, I can cite at least one good outcome of advance in science and technology.

The extinction of the dinosaurs. I mean yes, it allowed the growth of large mammals and us, which did a lot for science.

I just don't want to write the next chapter as "The extinction of humans allow the growth of the computing civilization that went to the stars". I mean I'm a bit attached to living.

>Nobody knows the extent of the impact. Who says otherwise is foolish.

We live in a universe of statistical probability. Creating an agentic intelligence that's smarter than you tips the probability of a major event to unity, who says otherwise is foolish.

Because we humans haven't had a bad enough history event yet, like a global thermonuclear war. Or perhaps climate change reaching tipping points driving the temperature up past what global civilization can adapt to in time.
