Episode notes

Formal physics knowledge is not essential to perform physics in the real world. Historically, there was a belief that AI could not understand physics because it lacked formal physics education, limiting its ability to solve complex physics problems beyond first-order reasoning. However, advancements in technology have shown that with sufficient computational power, physics can be performed instinctively, much like how a cat can jump or a bird can fly without needing to comprehend aerodynamics. This challenges the notion that formal physics theories are crucial, suggesting that they may not be as significant as previously believed.

“There is this move from generality in a relative sense of ‘we are not as specialized as insects’ to generality in the sense of omnipotent, omniscient, godlike capabilities. And I think there's something very dangerous that happens there, which is you start thinking of the word ‘general’ in completely unhinged ways.”

In episode 114 of The Gradient Podcast, Daniel Bashir speaks to Venkatesh Rao.

Venkatesh is a writer and consultant. He has been writing the widely read Ribbonfarm blog since 2007, and more recently, the popular Ribbonfarm Studio Substack newsletter. He is the author of Tempo, a book on timing and decision-making, and is currently working on his second book, on the foundations of temporality. He has been an independent consultant since 2011, supporting senior executives in the technology industry. His work in recent years has focused on AI, semiconductor, sustainability, and protocol technology sectors. He holds a PhD in control theory (2003) from the University of Michigan. He is currently based in the Seattle area, and enjoys dabbling in robotics in his spare time. You can learn more about his work at venkateshrao.com
