Must Read - True Strategy for the Age of AI
Format: Hardcover
I'm a management consultant and an entrepreneur reading these kinds of books for more than 30 years. It took me only 5 days to read this book. But it took me another 5 days to summarize all my notes and thoughts and share with my team. And I think it will take me more than 5 years to implement and build everything inspired and suggested by this book.
Sangeet explains in a very fluent, structured and captivating way, with real world examples, how business models change, how AI plays a critical role. We does eliminate all the hype about AI fiction but he focused on AI facts.
Strategy is not about how to invest in AI, it's about "where to play" and "how to win."
Read this great book, get inspired, and change everything you think you knew about AI and business strategy.

Reshuffle Just Reshuffled My Perspective
Format: Paperback
Reshuffle completely reshaped how I think about Gen AI and disruption. Sangeet Paul Choudary does a brilliant job of weaving real-life examples with practical frameworks, making big shifts in tech feel both understandable and actionable.
What I loved most is how he pushes the conversation beyond the usual “AI won’t take your job, but someone who knows AI will.” Instead, he asks the tougher question: what if the job itself no longer exists because of AI? It’s bold, thought-provoking, and incredibly relevant for anyone navigating change right now.
This book feels less like theory and more like a roadmap — one that left me reflecting on my own work and excited about the opportunities ahead. Highly recommend, especially if you’re looking for fresh ways to think about leadership in the age of AI.

Overall sound thesis worthy of thoughtful consideration
Format: Kindle
Choudary’s book has the tag line, “Who wins when AI restacks the knowledge economy.” While the book is annoying in sections, vague in others, and prone to jargon in yet more locations, the basic thesis is sound and compelling. It’s worth considering.
Choudary’s main argument is that the winners after AI technology is widely adopted will be those who take a systems view of their business rather than simply upgrading individual elements within it. He backs this with several examples based on past technological disruptions and hypothetical case studies. He argues that the best advantages from AI will come from improved communication and managing risk. He supports these arguments reasonably well within the chapters. He also includes 10 Takeaways at the end of each chapter, which is extremely helpful for recapping and making sure the reader understood the thesis.
What gets annoying is Choudary goes back to the same case studies again and again and again. I reached the point of saying, “the horse is dead. Please stop flogging it.” Next, some of his arguments about things like “managing risk” are vague—there’s not enough about specific risks to be useful, which leaves AI as a magic wand to wave. Finally, as with many business writers, Choudary occasionally (but not overwhelmingly) drops into jargon like “technological solutionism.”
Overall, I recommend the book. It’s made me think, even as I struggle to apply the principles to my own business.
