The answers aren’t deterministic. Which is part of the problem. While searching for these now may give you the right answers, I have personally encountered this level of bad responses enough times that none of these are surprising.

There’s no need to doctor screenshots to get these responses, at least twice now Google has shown bad answers in their own marketing materials.

Plain old web search wasn't deterministic either. At least for the past decade or more. I mean different people getting different results.

It pretty much was deterministic before Google started using ML to "help" interpret your search queries, which was a decade or more ago. Not coincidentally, that was also when Google search results started getting noticeably worse for me.

I have come back to some really tricky problems days or weeks later and the AI crushed it after having issues initially.
