I remember someone posting a chat thread from one of the more advanced AIs within the last few years wherein they asked it who the president of the US is, and it was not able to answer.

Interestingly, this is a question my father would ask patients as a paramedic who was trying to assess people's consciousness. Another would be, "what day of the week is it?".

I'd say that these technologies are just like magic - they can seem to do things that defy your expectations, but oftentimes they fall apart when looked at from a different angle.
