I think that's a typo on the user's behalf, it seems counter to everything they wrote prior. (And Bing is already adamant it's 2022 by that point.)

Plausible. It seems to me the chatbot would have picked that up though.

There's a huge incentive to make this seem true as well.

That said, I'm exercising an abundance of caution with chatbots. As I do with humans.

Motive is there, the error is there. That's enough to wait for access to assess the validity.

From the Reddit thread on this, yes, the user typo'ed the date here and tried to correct it later which likely lead to this odd behavior.
