> This is precisely what the people worried about AI risk and job displacement want, so they should be strongly in favor of open weights then, right?

I'm getting a "gotcha" vibe from how you worded the question, but the answer -unironically - is "Yes." Anyone who is not a closed-weight AIaaS provider[0] will have their lot significantly improved by equally capable, open-weight models.

0. Or their investors. I'm surprised to see Y Combinator signed this letter sering their holding in OpenAI is worth billions and hasn't IPO'd yet. I suspect they crunched some numbers first before signing.

Edit: I realized another group that may be unhappy with frontier open-weight models are those who believe LLMs are inchoate super-intelligences; not only do I disagree with them, but if they are correct, I don't see why we should trust trillion-dollar corporations and their out-of-touch CEOs with that responsibility, when countless CEOs have shown time and time again, that they are not aligned with humanity's interests.
