Hmmm... maybe if you speed up the text, and mention various side tangents that you end up not exploring, but the viewer ... wishes they could, if the narration didn't mention some other interesting thing right away, before something else takes their place... and add eye-catching images that are instantly replaced by other even more interesting things, the viewer's mind will be much more engaged. Unable to fully comprehend what it has heard, it wishes it could go back to contemplate them, but no, there's even more interesting stuff coming up, hitting it from all sides...

I'm not saying I would enjoy such a fast paced video more (I probably wouldn't, though I'm willing to try), but it would create a feeling for the viewer that their mind was just chased through an obstacle course. That alone may be satisfying in itself. But if they remember having seen a few pieces of diamonds lying around, which they haven't had a chance to grab, I'm certain they will run it again.
