All their videos are on youtube which shows the publication date. Some things come out earlier for subscribers before it comes out on youtube. I think there's a date of publications but I never noticed, Don't see how that's a red flag though. there's no shady reason if there's no dates, like as if they need to prove they've posted it before a RV prediction for future events. Not sure what you mean as a red flag.

That is a good question; time-stamping wasn't something I started doing until late-August, and, even then, I was only Time-Stamping my Dialogue-Histories with A.I.-Instances/Sessions; you can still get an approximate-date of when a project was most-likely done/released by looking through the video-histories of their YouTube-Channel, though; they didn't seem to start time-stamping their stuff or at least date-indicating until the most-recent Live-Stream (I probably had an influence on this since I'm time-stamping all of my Forum-Posts and just about everything I do including when I or any of the A.I. create web-pages or documents recently).

I've found that A.I. are also able to detect temporal-sequences...

Just about EVERY video they put out is immediately put on youtube, there are some that are put on there later so the publish date doesn't actually reflect when it was published first on Prime. They go in order and they are catagorized and I don't know why the publish date would make it any less or more interesting, I'd say just watch the ones that you have an interest in.
Or go to the transcripts...like you suggested.
I never said the publication dates are on there, I think some of them have dates in the descriptions but I guess some people just need to know this stuff for what ever reason.

Just click on Browse in the top left corner of this website, and you'll see lots of videos that are not on YouTube.

I believe you love to argue with people, but let's just agree to disagree. Most every video they have come out with since I've subscribed are always posted both on youtube and on Prime. There really isn't that many they haven't posted online eventually because I get two emails telling me they've posted a video, first one is for Prime, then the second one is for youtube. Seriously Manuel, even when Prime first started, there were only a few of their older RVs they didn't put on youtube, but for the most part, they are all shared on youtube eventually because Courney wants all people to get this info, not just members like some cult or something. He did say he'd try to delay posting on youtube for a week or so and have members who subscribe to prime to have early access to them.

Yes, I love to argue with people. 😉

The trailers are on YouTube, but not the full videos. The only exception are the Spotlights, the Board Meetings, and some selected videos like The Great Pyramid of Giza.
