I had a nice discussion with Robert Wright on his podcast Nonzero on the technical workings of AI aimed at a nontechnical audience. We go into the details about transformers (the architecture underlying models like ChatGPT), aimed both at a high level understanding as well as going into the weeds of the internal mechanisms. Along … Continue reading How Does AI Work?

Ever wanted a technical understanding of the Many Worlds Interpretation of quantum mechanics? Then join Sean Carroll and I at The Cartesian Cafe for a mathematical-philosophical whiteboard session on the foundations of QM and emergent spacetime: https://youtu.be/LGtimjuA5gA We start with a basic overview of textbook quantum mechanics: states in a Hilbert space, the Schrodinger equation, … Continue reading Sean Carroll | The Many Worlds Interpretation & Emergent Spacetime
