3 minutes is too long for exploratory searches, where I'm not sure what I'm even looking for. And 3 minutes feels too short for deep research which I'm expected to trust some complex result which I either don't know enough about myself (that's why I'm searching for it) or know enough about to the point that AI probably can't do something that I already couldn't within a couple minutes.

I think the sweet spot for AI results is around 10-30 seconds. It's fast enough that I'm willing to wait for the results even if I'm not sure I'm exploring the right topic. And it's also fast enough that even if I knew what to search for, it can give me summarized results faster than I could read on my own.
