A lot of this self censoring is algorithm voodoo. Nobody knows what makes these platforms mark your videos as age restricted, so people do silly stuff like say, “unalive”. I’ve seen many videos where people use the word kill that aren’t age restricted.
I’m not convinced statistics can be used like this on big questions where we know so little. Just because we believe the universe to be massively large and ever expanding doesn’t satisfy the basic premise that underlies the assumption that there is so much stuff that some of the stuff must be alive. I don’t think we know enough about the universe to make the assumption that because it is so big, it must be infinitely variable.
But what do I know, I’m just some idiot on the internet.
