New York also wants 3d printers to know when they are printing gun parts. Sure these initiatives have good meanings but also would only work when "the good ones" chose to label their content as AI generated/gun parts. There will _never_ be a 100% sure fire, non invasive, way to know if an article was (in part) AI generated or not, the same way that "2d printers" (lol) refuse to photo copy fiat currency, to circle back to the 3d printer argument.
IMO: it's already too late and effort should instead be focussed on recognition of this and quickly moving on to prevention through education instead of trying to smother it with legislation, it is just not going away.
