I think one attack vector where anthropomorphisation is a key part of the attack mechanism is - as it already is IRL - the meat-bag weakest link ie. social engineering. We’ve already seen humans fall prey to the seductive charms of LLMs (eg. depressed people encouraged to do what was already on their minds ie. suicide). And that’s knowing that it was an LLM. If you think it’s only depressed people or the “weak minded” that are amenable to an intentional attack using this approach, I believe you’re mistaken - especially as AI improves. An unaligned LLMs most important weapons won’t be a robot army - it will be hoodwinked humans.
