A Chatbot Said 8 Hours. The Climb Took 16.

This story is not from shipping. It is about a mountain. But anyone who has asked a chatbot a quick question at work should read it.

What happened. In early September, three young hikers in California used Google's Gemini chatbot to plan a climb of Mount Shasta, a 14,000-foot volcano. The chatbot said the climb would take about 8 hours, so they took little food and water. It took 16 hours. They reached the top at 7 in the evening, came down in the dark, one of them was injured, and they were rescued the next morning. The sheriff's office told climbers never to rely only on AI to plan a trip.

Not the only case. In July, two hikers in Poland's Tatra mountains followed ChatGPT's advice onto climbing terrain and had to be lifted out by helicopter. Rangers on Mount Shasta report other cases, including a visitor who camped next to a "No Camping" sign because AI said it was allowed.

Why it happens. Researchers point to one simple thing. A person who is not sure hesitates, and we notice. A chatbot has nothing built in that shows doubt. A wrong answer sounds exactly as sure as a right one.

Why it matters at sea. Crew and office staff already ask chatbots about port rules, procedures, weather, equipment and regulations. Most answers will be fine. A few will be confidently wrong, and they will look exactly like the good ones.

What to do. Use chatbots to start the work, not to finish it. For anything about safety, rules or a port, ask the chatbot for its source and check it. Teach crew one habit: if the answer matters, confirm it with a person or an official document. And when you choose AI tools for work, prefer the ones that show where each answer came from.
