Did he conclude it was a starship or argue we shouldn't dismiss out of hand that an object like this has a non-zero chance of being an artifact of another civilization?
I mean, he titled his book about it “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth”.

I’m very onboard with “it was an interesting object and we should learn more”.
I object to UFO cranks jumping to “it was a starship” conclusions like Avi Loeb wants to. Just as I would have when those weird first exoplanets showed up.
