Mind Matters

In this bingecast installment of the Mind Matters News podcast, host Robert J. Marks welcomes economics professor and author Gary Smith to discuss the hype around artificial intelligence and its impact on the market. Smith is the Fletcher Jones Professor of Economics at Ponoma College and a frequent contributor to Mind Matters News. Smith argues that generative AI, embodied in services like ChatGPT and Google’s Gemini, exhibits many characteristics of past market bubbles, including excessive hype, lack of profitability, and unrealistic expectations. Smith holds that generative AI models have limited practical economic value. They may be good at finding statistical patterns but struggle to distinguish meaningful, useful correlations from coincidental ones. Smith describes the fundamental challenge of teaching machines true understanding that goes beyond mere pattern recognition. A number of examples and stories are shared throughout.

On this bingecast episode of Mind Matters News, host Dr. Robert J. Marks welcomes to the podcast Dr. Mihretu Guta to discuss one of his chapters in the volume Minding the Brain titled “Mirror Neurons, Consciousness, and the Bearer Question.” Dr. Guta discusses the concept of “mirror neurons” – a type of brain cell that fires when a person observes an action being performed, as well as when the person performs the same action themselves. The properties of these neurons suggest they may play a role in empathy and understanding others’ actions. Dr. Guta explores the implications of mirror neurons to the mind-brain debate and how further study could illuminate these fascinating neural components.
