ChatGPT is an artificial intelligence chatbot that has been making headlines since its launch in November. It is well documented that the chatbot is knowledgeable, friendly and smart, but its answers are proving to be highly erratic. Examples of its mistakes, referred to as hallucinations, include its explanation of why adding broken porcelain to breast milk can help with an infant’s digestion, and its inference that four cars would take four hours to drive from A to B. The best use for the technology is still being debated.
