Besides, I would assume that someone who was genuinely concerned about the direction of AI research would want to amplify their voice, as he obviously did by his resignation post on Twitter and then having that picked up by prominent voices. That doesn't make it some sort of nefarious astroturfing campaign. And there was tons of genuine fear before this guy resigned when the details from the Hugging Face and other attacks came out.
Plus, that Twitter link you posted obviously has some weird tribal bone to pick against Democrats, as if there is some sort of Democratic conspiracy against AI. Yeah, does he think this guy is a Democrat?: https://x.com/HawleyMO/status/2098137180392604083
