The hallucination of messages bothers me severely. Especially with AI being deployed to ancient, difficult problems like the Herculaneum scroll.

EDIT: To be clear, I'm talking about the "Written in Morse Code" example, fully hallucinated text. The AI agents seeing a decoy message isn't as bothersome to me.

It's not fully hallucinated, I don't think. If you squint, you really can see what I assume is the 'decoy message', I'm fairly sure it says 'WRITTEN IN GHOST FONT'. It seems more likely to me that the LLM found 'Written In', noticed similar 'optical illusion' type memes, and hallucinated/assumed the 'morse code' bit.
