It challenges the assumptions around "accessibility". some linters might (blindly) suggest aria labels, where the author is suggesting otherwise. That is worth the 3 min reflection that this article took to get through eh?

"an article about a button not being a submit button"

This is just one of the points the article is making, and it isn't that the button isn't a submit button, it's that the button returned by the LLM has both characteristics of a submit button, and characteristics of a regular button.

I personally found the article interesting.
