AI is a very different problem space. With AI, even the big models easily fit on a micro SD card. You can carry around all of GPT4 and its supporting code on a thumb drive. You can transfer it wirelessly in under 5 minutes. It's quite different than drugs or conventional weapons or most other things from a practicality perspective when you really think about enforcing developmental regulation.
Also consider that criminals and other bad actors don't care about laws. The RIAA and MPAA have tried hard for 20+ years to stop piracy and the DMCA and other laws have been built to support that, yet anyone reading this can easily download the latest blockbuster movie or in the theater.
Even still, I'm not saying don't make laws or regulations on AI. I'm just saying we need to carefully consider what we're really trying to protect or prevent.
Also, I certainly believe that in this case, the widespread public adoption of AI tech has already driven education and adaptation that could not have been achieved otherwise. My mom understands that those pictures of Trump being chased by the cops are fake. Why? Because Stable Diffusion is on my home computer so I can make them too. I think this needs to continue.
