> I think having people with courage to stand up and argue against the consensus is incredibly important.
I agree it would be nice if Loeb tried that. So far he hasn't made any arguments, just bloviated.
And what "consensus" do you imagine Loeb is your champion against? Tarter is a pioneer carving out a new discipline, not the latest head of some ancient SETI cartel started by Aristotle. Any "consensus" is tentative at best. To hear Loeb speak, you would think it were he who started searching for techno-signatures forty years ago--with Tarter in a dominatrix outfit and a whip waylaying him at every step.
He yelled over her, refused to let her speak, misrepresented her arguments, and tarred a diverse research community with a broad brush. Nobody made him show his own ass on Zoom. That was his choice.
By contrast Tarter was polite, gracious, and statesman-like. She defended her colleagues clearly and let the clown dig his own grave. Never interrupt your enemy when he's making a mistake. If I were one of the researchers she were defending, I would be proud to have her up there representing me, and certainly glad I wasn't the one who was asked to find time in my research schedule to act as some narcissist's punching bag for an hour so he can build his social media viewership.
Loeb is just another science grifter who pumps up bad ideas with hot air in order to make some post-truth money off rubes who watch Joe Rogan--where making wild and evidence-free claims made with a flourish of performative masculinity beat decades of careful research.
