And what is the reality of the capabilities of AI now, and in the future? AI has always stirred emotions, and caused great excitement as well as great concern. Since the launch of large language models such as ChatGPT, the scope and capabilities of AI look set to transform our technology, in both good and bad ways.

Focusing on specific AIs and their creators over the years, it explains the science and engineering behind each AI, discusses ethical issues and covers all the most fascinating information about one of the most important and contentious developments in human technology (including the latest on generative AI/ChatGPT), as well as what we can expect to see in the future of this field all in short, accessible bite-sized chunks.
