Very common for this format. It looks and sounds like something of substance on the surface, but ultimately it's just going through the motions and droning on to fill 10 minutes. Like a high-schooler with an assignment to give a presentation on some topic, but with higher production quality.

It does not have to be coherent, because it's entertainment, closer to a sitcom than educuation. If you think about it too hard you'll ruin it for yourself.

Before you blame YouTube and AI though, have a look at what documentaries on TV are and used to be like. With few exceptions they're not much better.
