I am opposed to a flat-out ban on ChatGPT, because I do believe it can be a useful tool (see below), but there do need to be rules (and common sense) around its use.
A ChatGPT-based answer should never be posted by someone without subject matter expertise in the question being asked in the first place. Confirming that the answer works is not enough. If you are even using ChatGPT to assist you in crafting the answer, then you must have the ability to:
- Confirm that the answer is correct and works
- Fully understand the answer that you are posting
- Correct any issues
- Communicate the answer in your own words
- Reply to follow-up questions/comments about the answer you post
- Warn of corner cases or potential issues if needed
- Cite any reliance you made on ChatGPT for the answer
If I was answering a question like this on a Stack Exchange site, then the extra information that ChatGPT provided would be useful in my answer as long as I could Confirm, Understand, Correct, Communicate, Reply, Warn, and Cite as mentioned above.
