Basically, governments and laws can be fairly slow to adapt. Consider that it wasn’t that long ago that you could absolutely tell that something was made by AI whether it was caused by stilted/unnatural speech or mangled fingers in fake pictures of people. In a few short months we’ve gone from dreamlike hallucinations of real things, to almost passable renditions. AI is just advancing too fast for most governments to make a decision and formulate a coherent and mostly future proof set of laws regarding it.
