That's an important point, and and it ties into the way ChatGPT and other LLMs take advantage of a flaw in the human brain:

Because it impersonates a human, people are more inherently willing to trust it. To think it's "smart". It's dangerous how people who don't know any better (and many people that do know better) will defer to it, consciously or unconsciously, as an authority and never second guess it.

And the fact it's a one on one conversation, no comment sections, no one else looking at the responses to call them out as bullshit, the user just won't second guess it.
