Unsure how much information on this can be shared, if any, but I'm curious what criteria is considered when deciding to open a new board. Even as a janitor, it's a very opaque process that doesn't seem to follow any consistent logic (observable).

I can offer a few examples from the newer boards.
/vt/ was obviously created due to immense demand for it, and it has quickly grown to becoming one of the most active boards on the site. In contrast, it feels like it's been well over a decade of users begging for some kind of internet celebrity board and those requests have gone unanswered, despite the fact that there is clearly interest in it (/v/ janitors will have firsthand experience seeing this demand from deleting threads on this subject). What's the difference between these two things? Is it just a subjective thing, that the 4chan team does not want standalone boards dedicated to certain topics?

Then at the same time, we get boards like /qst/ or /vmg/ that don't even get 1000 posts in a day and nobody was really asking for, so clearly demand isn't the only thing considered, or even necessary.

For my part I'm asking this because I think it may be worth considering some kind of /ai/ board for posting AI generated content, whether it be audio, images, video, text, etc. /g/ has several ai related generals and most don't discuss the technology but are instead just dumping grounds for content, and I think there's an opportunity here to separate that space and allow it to scale. It's just hard to argue for this when I don't really understand what the common thread between newly created boards is.
