AI hallucinations are going to be the new database query injection. Saying that real time internet connected fact checking will solve that is every bit as naive as thinking the invention of higher level database abstractions like an ORM will solve trivially injectable code.

We can't even make live fact checking work with humans at the wheel. Legacy code bases are so prolific and terrible we're staring down the barrel of a second major industry crises for parsing dates past 2037, but sure LLM's are totally going to get implemented securely and updated regularly unlike all the other software in the world.
