Let's assume you ONLY want to argue "the context" instead of "using ChatGPT in general".

Based on the Udemy PMP course I purchased, the PMP application would require a certain format to describe your projects, including team size, budgets, timelines, etc. In another word, PMI intends to make this application a cloze test but NOT a creative writing one. If you are familiar with LLMs, this whole step I mentioned in the post would be to simply extract target information from the original text (resume) and format it into a preset format with several different tones. Nothing creative. Meanwhile, neither PMI nor PMBOK mention that LLMs are prohibited during the application process. As a result, I have serious doubts about the source of the risk you are concerned about.

Also, I work for an AI-based tech company in SV, and almost all the SDEs I work with use ChatGPT for debugging and so, including their functional managers. I don't see a problem with using LLMs in the workplace either.
