His Galileo Project is explicitly looking for “extraterrestrial technological signatures”, and he’s just using any opportunity for hype about that.

He got attention for writing about this for Oumuamua, and now he’s just rinsing and repeating for 3I/Atlas. It’s exactly like any youtuber chasing the most effective clickbait.

It’s like when Altman talks about AIs building a Dyson sphere. Everyone with any understanding of the issues knows it’s self-serving hype.
