I see a lot of questions that I find frivolous, or that bring up familiar yarns from 2000 years ago or more, and I often wonder if this is the place to entertain such rehashing. There really should be a Philosophy 911 phone line.
But anyway, what about questions that seem to be pure, unproductive speculation about things that we can probably never know or come to any conclusions about? I'm thinking of questions about whether other intelligent beings exist, or if they have embroiled us in a universe-wide simulation or other such things that can have no bearing on life or practical matters.
Personally, I would dismiss those instantly, but if there is some good reason for sponsoring these, please let me know. And, if there is a Close Reason related to this type of thing, I'm going to use it.
