Sabine's early video's seemed pretty sincere, and had a lot of valid points. But later, I think the pressure of creating constant content, and moving into non-expert areas, has gotten just as pop-sci as anybody else. Still think she is on another level from Eric who will throw out any crazy idea he can if someone will listen.
She has gone way beyond this. She is actively undermining the entire academic scientific enterprise, even as she makes money popularizing it. It's unclear why she does this. She portrays herself as speaking truth to power, but -- much like certain actors in US public life these days -- is simply doing the easy work of tearing things down, without doing the hard work of building things.
