This is a great telling of the race to create a general purpose artificial intelligence that sparked the ChatGPT LLM frenzy that is fueling a craze for AI. It is interesting how two companies both approached the challenge with a focus on AGI and safety and how they both ended up getting co-opted by the very tech giants they were seeking to shield the technology from. Well-told and well-researched, I really enjoyed reading this. The book does a good job at not taking sides as either a techno-optomist or and AI-doomer and presents both sides evenly. Well done!
