We’ve been living in Valle de Bravo – a mountain town a couple of hours outside Mexico City – for 9 months now. I’ve lived in 5 countries for at least 6 months each, and traveled in another 20, and I think this is the most perfect place I’ve ever encountered for an expat family…
In 1997, a young hip-hop producer from Detroit named J Dilla did something that violated every rule in music: he programmed his drum machine to play “off beat.” Not just slightly off, but deliberately off—breaking up the rigid timing that had governed musical performance in every genre. What happened next confounded the music industry. Instead…
I’m proud to introduce Death Clock, a life expectancy calculator that predicts the day of your death based on 17 personalized variables. Give it a try for free! This is not only the first “app” I’ve ever created myself, but also my first experience with AI-assisted coding, which has become known as “vibecoding.” I can…
I recently came across a Substack post by Venkatesh Rao called Oozy Intelligence in Slow Time that was one of the most insightful I’ve ever read for understanding the nature of Artificial Intelligence. We tend to think of Artificial Intelligence as being in an arms race with Human Intelligence. Which one is smarter? When will…

Throughout that time, there has been one question I’ve been trying to answer: Will AI replace the need for Second Brains entirely? A lot of people seem to think so, and I admittedly have a self-interested motivation: to decide…
I recently came across an interesting guide on how to train ChatGPT to write in your own voice and style. It is part of the Substack publication Write With AI, by Nicolas Cole and Dickie Bush. I decided to give it a try because if I succeeded, this would solve one of the biggest problems…
Two books I read recently helped me tremendously to understand what’s happening now with Artificial Intelligence: Prediction Machines and Power and Prediction (affiliate links) by Ajay Agrawal, Joshua Gans, and Avi Goldfarb. The authors are economists and professors at the University of Toronto, one of the leading institutions studying the economic impacts of AI. Their…
Imagine a product manager sitting down with his team on a Monday morning to plan the next week. The main item on the agenda is the decision of whether to create a mobile app for their e-commerce website. The team quickly gets excited about the idea, imagining all the possibilities it could entail. They propose…
I recently sat down to attempt something I’ve been dreaming of for a long time: using Artificial Intelligence (AI) to automatically create a high-quality book summary. As I wrote in my Ultimate Guide to Summarizing Books, writing book summaries is one of the very best ways I’ve found to absorb an author’s ideas deeply into…
