Greens are treasures for humanity, and they did a lot of great. But previous achievements shouldn't make you immune to criticism. And this is exact topic that should cause harsh criticisms. Hank is an educator, and the only good educator is one that has absolute trust of his audience. Right now his reaction to a backlash is exactly ideal one so I have good hope for the future, and I'm afraid it might not be so if the backlash wasn't as harsh.
The whole reason Hank is so great is that his team does proper research, and they're not afraid of showing their mistakes and correct them. If they start relying on LLMs, all of that can be thrown out of the window, you couldn't trust anything anymore, LLM's whole thing is that it breaks your brain into relying on it, as evident. A pop science video isn't good at all, if the viewers will have to double check every point.
So this is exactly correct reaction that should be modeled for all such occasions in the future, from both parties actually. And in Green's case, their previous legacy gives them enough social credits, that I totally trust him to be smart enough to reevaluate his processes and come up with safeguards, and if he actually does it, this will award him more trust.
Don't conflate accountability with blind hate.
