I mean yeah... if he had a solution they would be actually have the revolutionary AI tool the tech writers write about.
It's kinda written like a "gotcha" but it's really the fundamental problem with AI. We call it hallucinations now but a few years ago we just called it being wrong or returning bad results.
It's like saying we have teleportation working in that we can vaporize you on the spot but are just struggling to reconstruct you elsewhere. "It's halfway there!"
Until the AI is trustworthy enough to not require fact checking it afterwards it's just a toy.
