I know people who know lots about their own domain. The instant you go to zoology or niche astronomy or architecture or whatever I have large doubts on the breadth of their knowledge. I do not have my doubts with Astra at all. It'll just search the internet for a good source (or 50) and get the correct answer.
Not every answer is on the internet.
So, what you are saying is Astra is not really smart, it just has access to the internet while your friends don't.
I'm pretty sure 'Who wants to be a millionaire' and the likes would work very differently if the contestants could search the internet for the answer.
