Has anyone read any good technical books about how to get the most out of Chat-GPT, especially on prompt engineering?

Has anyone found any exploit in it? LIke if you use any kind prompt and the chat gpt become uncensored ? Like when you ask it about hacking method it doesnt give you anything!

Now that we have Chat GPT, are writing tools such as Jarvis/Jasper etc. obsolete? Or is there still a use case for them?
