Air traffic control software is not going to be vibe-coded anytime soon and neither is the firmware controlling the plane.

Sure it will. But they will be tested far more stringently by both human experts and the smartest LLM models.

I will be perfectly honest. Given what I am seeing, I fully expect someone to actually try just that.

Considering how much work at Boeing is given to consultants and other third party contractors (eg famous MCAS), some piece of work after moving through the bowls of multiple subcontractors will end up in the hands of a under-qualified developer who will ask his favourite slop machine to generate code he doesn’t exactly understands purpose of.
