Another give away that the article wouldn't be in good faith is that weird rant in the beginning about how OpenAI didn't share with them research access.
I think people don't talk enough about useful prompts and most demos don't bother sharing their prompt. I think people thinking about building businesses off gpt3 see their prompt as essentially their secret sauce. And maybe other tuning parameters, but there really aren't too many. You can turn up the temperature and maybe build a model to score the response or fine tune the model.
