This looks AI generated.

There are places where it includes citation references like [15] (search for "on complex problems" on https://appetals.com/promptguide/advanced-techniques-for-pow... ) that are just text, they don't resolve to anything.

Other places repeat the same point twice for no apparent reason - the "Context window" section on https://appetals.com/promptguide/understanding-the-machine-m...

I spotted a few "not X but Y" constructions, like "You'll learn to communicate with AI like a pro, not like someone shouting into the void."

I don't think reading this is a good use of your time.
