The comment was sarcastic, hence the "/s" at the end of the first sentence. Everything else was a thought experiment to show how the idea of LLMs on everything including commercial planes is a very bad idea and would give regulators a hard time. The point is: just because you can (build and run anything) does not mean you should (put it on commercial planes).
