I have written a decent amount of math content. On the internet, and off the internet.

Do you want to get into a sentence-by-sentence analysis?

I have pointed out one reason: because the text titled "visual introduction" lacks visuals, and the introduction of complex number in it is purely algebraic without a single picture.

The numbers are introduced algebraically, and then explained visually, after the reader was already confused. You only get anything out of this if you already know complex numbers well enough; in which case it's not an introduction anyway.

The author says, quote "I did use AI assistance for some of the components", so I hope this settles the discussion as to whether it's AI slop or not.
