Who I'm Following - February 2026

The Experimentalist	The Contrarian	The Decision Scientist
Ethan Mollick doesn't just write about AI—he runs experiments. His Substack "One Useful Thing" is the most practical, least hype-y AI content I've found. Every post includes something you can actually try. Follow him if you want to stop theorizing and start testing	Rishad Tobaccowala spent decades at Publicis and now writes with the freedom of someone who no longer needs to please anyone. His takes on leadership, transformation, and the future of work are sharp, sometimes uncomfortable, and always thoughtful. His "Re-Thinking" newsletter is worth your time.	Cassie Kozyrkov is Google's former Chief Decision Scientist and now CEO of Data Scientific. She founded the field of Decision Intelligence, which is essentially the argument I keep making in different words: data is only valuable if it improves decisions. With over half a million followers, she manages something rare—making AI and statistics genuinely accessible without dumbing them down. If you've ever laughed while learning about machine learning, it was probably her fault.
