Overall Satisfaction with ChatGPT
I use ChatGPT constantly as a Consultant and Project Manager in my client and personal business work for preliminary research, writing purposes (such as emails, one pagers, white papers, etc.), I have it outline templates, tables, and programs for me, and my favorite function is using it for setting up Excel and Google sheets formulas and spreadsheets, including Google Scripts.
Pros
- Creating spreadsheet formulas and set-up instructions (ie. Apps Scripts and Macros)
- Brainstorming ideas and lists of questions to ask yourself and others (ie. In meetings and interviews, when developing a business plan, etc.)
- Writing emails
Cons
- Statistical figures are often wrong and ill-cited. For example, for a presentation, I was trying to cite statistics and comparisons as to how rare one event is versus another, and I got different outputs every time. These answers were not reliable.
- I can never trust ChatGPT math. Even simple equations are sometimes miscalculated, and when dealing with large numbers, small errors or rounding discrepancies result in wildly inaccurate figures.
- Unorganized/inaccurate sources. When I ask ChatGPT to cite sources, it doesn’t cleanly quote where it got each point from. And if you read the cited article, the figure/info it provides might differ from ChatGPT’s output.
- ChatGPT has had a positive ROI on my personal business objectives and administration budget as it has saved me plenty of time when writing emails.
- Positive ROI on client work in generating templates, outlines, and starting points and research for my client work. Saves me time and labor, allowing me to take on more clients.
- Positive ROI on design. Aids in my creativity by helping me name my business and spark ideas. Saved me from buying a logo or brand manager or creative consultant.
ChatGPT is often seen as the default and the leader and first and most widely adopted generative AI engine. However, I tend to find that Google Gemini can more accurately cite sources and offers more disclaimers. ChatGPT is prone to answering everything, at the risk of providing false or misleading answers.
