Guy did it for free man. Give him a little slack. He's not even a programmer. He does Mario speed runs. He didn't post his video here, someone else did.

And I absolutely disagree with the "Robot voice would be better." That's horrific.

i don't think he's picking on the authors themselves but on the broader problem:

How to make decent auto-play presentations on the web.

most of us hate it when scrolling gets broken. many of us like to simply watch a lecture go by with interaction, e.g. for deeper contemplation. many of us would like to hear the lecture.

stuffing it into a video is tradeoff.

this is just a typical problem of a highly-mediated era: we have the core information that can be rendered or published across numerous formats: book, blog post, tweets, video, google slide presentation, etc., etc. How to deliver the information to all formats, to be everything to everyone?
