1. Attention Issues - Attention is a finite resource that can't be expanded - Multitasking drains mental energy - Early screen exposure shapes developing brains 2. Pattern Processing - Natural environments have "scale invariant" patterns our brains process easily - Digital screens have "scale variant" patterns that strain our brains - Text on screens creates uncomfortable striped patterns 3. Impact on Young Minds - Declining motor skills from reduced physical activities - Reduced ability to delay gratification - Decreased emotional intelligence development - Interference with social skill development 4. Learning Impact - Over-reliance on digital tools undermines deep learning - "Calculator atrophy" - losing basic skills - Google creates shallow familiarity vs. true understanding - Real learning requires active engagement, not passive consumption

Core Problem: - Our brains evolved for Stone Age survival and aren't designed to handle modern digital information overload - Brain uses 20% of daily energy despite small size - Digital bombardment creates cognitive overload Solutions Suggested: - Reduce screen exposure, especially for young children - Spend more time in nature - Prioritize real human interaction - Balance technology use with hands-on activities - Focus on active learning vs. passive consumption
