On the other hand, when we critique, it is for the benefit of everyone who reads the critique and learns from it.

That's why critique has value. To the original author/artist (if they see it), but also to everyone else who sees it. "Oh, I was going to intersperse text slides with a transcript, but I remember how offputting that was once on HN, so let's skip the slides."

Text slides interspersed with the transcript work great normally.

But this is mostly slides with just four words of content, and a transcript that just be repeats the same words.
