Your eyes matter. Videos matter. It's just, they aren't the only things you should factor in. Why have ears, if sight alone is enough? Why have touch, if sight alone is enough?

What you are saying is, trust your eyes alone! Pay no attention to what you can touch or what people involved might have to say. That is the final and most essential command.

It goes both ways. With your eyes that you trust so much, hopefully you can see at least that.
