Even though it came out of X, I don't see how Chronicle could reasonably be considered a moonshot for Google. A cloud-based SecOps suite that emphasizes integration with Google Cloud/GSuite seems like a fairly obvious vertical expansion. That said, I don't know much about SecOps.
I'd argue that the OG Moonshot was less of a metaphorical moonshot than most of the X projects. Self-driving is obviously WAY harder than going to the moon, and I think we were way further away from a science and tech perspective than we were from the moon in the early 60s.

I don’t think that’s fair in the sense that going to the moon was absurdly difficult in 1962. It’s hard to compare things so different, but going to the moon only seems easier now, 60 years later. At the time of the moonshot it was one of the most difficult things humanity ever attempted.
