I've been told ChatGPT can't be trusted

Yesterday, I attended a university's end of the year senior design symposism. I spoke with an industry professional who had a long career designing medical devices and now serves as an expert witness in medical device trials.

He asked what I did, and I told him, "I'm the author of the recently published book, The Intelligence Tsunami ( I passionately believe the emergence of autonomous intelligence will transform the world."

While he quietly pondered that, I asked, "Have you ever used Chat GPT?"

"No, I've been told not to use it because it's not accurate and can't be trusted," he replied.

(I asked ChatGPT to create an image for a blog post titled "I've been told ChatGPT can't be trusted." Look carefully at the image it produced, and you'll notice the woman has three arms. Well, there you go. ChatGPT didn't intend to, but it showed it can't be trusted without checking its work. This expert witness shouldn't trust another human's work without checking it either, though.)

I told him how I had used ChatGPT and Google Gemini together to check the accuracy of chapters in my book. You can read about my experience in my blog post, "Is it accurate? is a powerful use case. Let's talk." (

Most people focus myopically on the fact that large language models like ChatGPT might be wrong. What's amazing about ChatGPT fact checking my book is that it connected a forty year old esoteric piece of data showing that something that I knew to be correct was actually wrong.

I told the expert witness that what's cool about fact checking with ChatGPT and Google Gemini is if you enter "Accurate?" and then the text, they will tell you if it's accurate and then give you bullet points about how they came to that conclusion. If they find that something may be inacuurate, they will give you bullets points that are leads to track that down too.

As we were leaving, he asked, "What's the name of your book again?" "The Intelligence Tsunami (," I replied. "I'm going to get a copy and look forward to reading it," he said. "Thank you," I said as we went our separate ways. Hopefully, you'll get a copy and find my stories interesting too.

Let's talk.

Let's inspire your team and your organization to excel.
