I agree with many of the arguments in this thread: that model-gatekeeping while publishing approaches seems insincere and just seems like it's daring bad actors to replicate.
However, a common refrain is that AI is like tools like hammers or knives and can be used for good or misused for evil. The potential for weaponizing AI is much much more so than a hammer or a knife. And it's greater than 3D-printing (of guns), maybe even greater than compilers. I would hazard to say it's maybe in the same ballpark as chemical weapons and perhaps less so than nuclear weapons and biological weapons, but this is speculative. Nonetheless, I think these otherwise great arguments are diminished by comparing AI's safety to single-target tools like hammers or knives.
