I think I might be a cosmic influencer (a bad influencer?)
There’s an asteroid named after me (22410 Grinspoon) which is better than having one with your name on it…

The possibility of finding evidence of other civilizations is one of the most profound and exciting scientific questions we can ask — but we must pursue it with rigor, not sensationalism. (6/7)

And they only serve to boost his ego, and book sales, while confusing and alarming the public, eroding trust in real science and harming the credibility and efforts of actual astrobiologists to build serious technosignature searches into a sustained and supported branch of science. (5/7)

The possibility of finding signs of ET technologies, what we call “technosignatures” is one we must take seriously. There are credible arguments for this, and some promising techniques for searching. (2/7)
