You're getting downvoted because it sounds like you're defending the topic at hand. It shows how most people don't understand the inner workings of an LLM. Hell, experts still aren't completely sure, but they ran with what was working and have been tweaking along the way when things got too ugly. And as also brought up, they used everything they could grab to make it happen without concern for legality or future backlash. For science... and profit. And I don't see a way to go backwards at this point, thanks to AI being embedded into everything (where it's suited and where it's not). For science... no, wait, that's definitely for profit. And also because of your points, there's no real way to filter or carve out what should have been restricted from being used, because it's not really there in that form. We need to do something and quickly, but we do have to work with the beast we've made.
Laws are notorious for being far slower than the tech it tries to control. And this time it can't be retroactive. Well, I mean, it could be... if we just ban all existing LLM and related AI work and start over. Good luck with that kind of legislation.
