An airline has a weather radar which shows the same thing for the same thing of weather event ahead. So, for similar weather phenomena, radar shows a similar thing.

For that thing, procedures and regulations are built. So regulations fit into a well understood phenomena, incl. "return back because that thing is way powerful for us".

For the same prompt, an AI model can return two completely different outputs, incl. but not limited to content, length, formatting and tiny details. What you get is a single instance. So, regulating an AI model for safety or any other property is not as easy as regulating air travel. Moreover, you have much stronger motivations for regulating airlines. Otherwise people die in a visible and gruesome way.

With AI, it's easy to whitewash problems. Somebody committed suicide? "They were already unstable". AI told something wrong and created problems? "The tech can’t guarantee truth because it's not alive, it can't understand right and wrong". It did something good? "It's probably a sentient being, we shall respect them".

I'm for regulating these things. They are dangerous as they are useful (sometimes), but the forces and motivations for regulating it is not the same.
