This week on the Only Human with Dr. Tony Kern podcast, Tony dives into how changes in technology have altered the “mental wiring” of the human brain through digital content. Far from a hand-wringing diatribe about the evils of modernity, this episode looks at the evolution of cell phone use over just a few decades, from a novelty to a ubiquitous item for daily survival. Along the way, he says we have yet to fully understand the dangers and opportunities this rapid evolution brings into the human performance equation.
