Co-Intelligence: How AI and Humans Can Work Together by Ethan Mollick presents an optimistic view of the future in which Generative AI tools complement and enhance human creativity, productivity, and decision-making. Mollick skillfully explains how healthcare, education, and businesses of all types will benefit from incorporating AI tools. However, the book falls short in addressing the critical ethical issues surrounding Large Language Models (LLMs). While Mollick touches on these topics, he fails to engage deeply with topics such as intellectual property, energy usage, and exacerbating inequalities. This review offers a critical analysis of Co-Intelligence, emphasizing the need for a deeper exploration of ethical frameworks to guide AI development.
