I'd be wary of any AI generated history video, history is already extremely easy for bad faith actors to deliberately misinterpret, and AI is going to compound those sources with AI hallucinations. If they were using AI to generate the video, I would think it is unlikely that they'd still be willing to put in the effort to put in proper research. A lot of what you might "learn" from a video like this could just be completely untrue, especially if it seems to be teaching you a lot of "new" things that you never knew about before.
