I'm wondering is anyone else is using 
ChatGPT to study for certifications. I find asking detailed questions that include the name of the certification vendors sometimes returns fairly accurate information. 
Consider the following question reworded in progressive levels of detail:
- what is defense-in-depth
- what are the layers of the defense-in-depth strategy
- what are the layers of the ISACA defense-in-depth strategy
- what is ISACA prevention, containment reaction, recovery, restoration
- what is ISACA PCRR model 
The information returned by ChatGPT a very nice alternative to traditional search engines for data mining information.
HOWEVER...
You will also see how different the results can be with only the slightest changes to the query. In the above list, bullets 4 and 5 returned two different descriptions of the ISACA PCRR model. I assume one is from older information and the other is the newer, revised model. ChatGPT does not return references of where it gets information, so it won't be replacing Wikipedia anytime soon.
Anyone else have any useful ChatGPT interactions or queries?
