Traveling through Italy, I used ChatGPT as a tour guide for the moments where my mom and I wandered into interesting little corners, alleys and buildings where our curiosity was piqued with no tour guide around. Salvador Rodriguez/CNBC As I stood with my mom under the blistering sun in Rome waiting for our audio tour of the Pantheon to begin, I decided to kill some time with ChatGPT. "Tell me about the Pantheon in Rome," I said.

The AI tool returned a bunch of information in bullet points that was helpful but hardly made for an interesting read. So I tweaked my prompt and gave ChatGPT a bit more info. "Pretend you're a tour guide and tell that to me in a more interesting fashion," I wrote.

My mom and I were in the midst of an epic seven-city trip in August to celebrate her 60th birthday. She had no idea that I was bringing along a digital companion. "Welcome, Chef, to one of Rome's most extraordinary treasures— The Pantheon ," the AI tool responded.

(I asked ChatGPT to refer to me as Chef several months earlier to make the banter more entertaining.) "As we stand here in front of this architectural marvel, let me take you on a journey back in time, where gods, emperors, and artists all intersect in this sacred space," the chatbot wrote.
