Unfortunately, the video is a far cry from carrying all the representative information: there is no way you can capture your full emotions as you are working through a problem, and where did you get your "eureka" moments unless you are particularly good at verbalising your through process as you go through multiple dead-ends and recognize how they lead you in the right direction.

And reviewing video would be a nightmare.

there are only two options: - have more information - have less information

more is better.

you can scrub video with your finger on an iphone. serious review is always high effort, video changes nothing.

Not really: I love reading fiction where I can imagine characters the way I want to based on their written depictions. When I see a book cover replaced with a recent movie adaptation actor, it usually reduces the creative space for the reader instead of enlarging it.

Video in itself is not more information by definition. Just look at those automatically generated videos when you try finding a review on an unusual product.

are you trying to evaluate the author for some certification or test? this is contextual to evaluation.

books are great.

hundreds of hours of video of the author writing that book, is strictly more information.
