ChatGPT is everywhere. From the weekend party table to the weekday university seminars, people have been talking about ChatGPT. Since its public launch at the end of last November, it reached 100 million users in January and has become the fastest-growing Internet service ever. GPT is short for generative pretrained transformer, and the chatbot is the large language model pretrained with text databases from the Internet and human feedback. The hype around ChatGPT may be well justified, as the tech innovation could transform some fields, such as how humans interact with machines. Will it be long before truly intelligent machines are developed to transform industrial sectors such as manufacturing?
