@Vlad I agree with @[deleted] completely. I'm here to point out that it seems impossible to fully disable "quick answer". I have auto-quick-answer switched off, but I still, without requesting or wanting it and with no ? in my query, get this (poor-quality) quick answer:

So it appears there are other, less-documented quick-answer triggers aside from ?, such as the word "Define". These ought to be disabled when I switch off auto-quick-answer; why are they not?
To be clear: do whatever it is you do to parse my search queries, but I do not ever want an 'AI' interpretation or summary of the search results. How do I get that, please?
