Tl;dr: The people who are freaked out about AI are the people who are bound to lose the most by it.

And some probably used ML assistance to contribute to the draft:

"At some point, it may be important to get independent review before starting to train future systems, and for the most advanced efforts to agree to limit the rate of growth of compute used for creating new models." We agree. That point is now.

This would lead to emphasis on algorithmic compute efficiency, quickly decreasing reliance on mega-actor cooperation! Hah!
