This book started as an experiment in how technical writers could use an AI chat bot to write technical content. ChatGPT (Generative Pre-trained Transformer) is a very popular chat bot from OpenAI, trained against a large set of written material on the Internet. The first time I experimented with ChatGPT, I was impressed with how well it could generate technical content. I wanted to see how far I could push ChatGPT to write a longer technical work.
