You’re probably not using GPT-4, the internet is being flooded with takes about GPT-3.5’s quality like this simply because the author doesn’t know there is a meaningful difference with the new model.
This isn't to say gpt-4 isn't cool or impressive or a development to watch and learn about and be excited about, but I frequently see criticism dismissed as "you must be using 3.5" while I find 4 still costs more time than it would have potentially saved.
