The actual criticisms you have about the content however, I'd like to challenge:
The "adding up to one" is just a simplified gloss over softmax. It's very possible it reads poorly, and thats on me - not LLM gibberish.
As for the incoherence - I have to totally disagree. You have merged the 2 things the post keeps apart - capacity and attention over it. That a model can swallow a schema and write code is a competence humans share. We have been doing it for decades. Besides, the claim was never about us sharing capacity (other than stating it is always bounded) - it was about our attention failing in eerily similar ways.
So, AI slop, no. AI assisted, absolutely. It's sad that some judge the "who" more important than the "what" - especially for this kind of writing. But it's fair feedback nonetheless. I'll see what else I can do with assisting my delivery.
