Dr. Poppy Crum discusses how neuroplasticity allows the brain to continuously reorganize in response to technology and experience, updating traditional models like the homunculus. Everyday interactions with smartphones and digital communication repurpose neural circuits, altering perception and social behavior. Video games and real-time feedback systems improve sensory processing and motor skills through closed-loop training. The concept of digital twins—dynamic digital replicas of physical activities or environments—enables personalized learning, health monitoring, and environmental optimization. AI can augment cognition but risks reducing germane cognitive load when overused, potentially undermining deep learning. Wearables and 'hearables' offer low-cost ways to track physiological states like stress via pupillometry or voice analysis, enabling early detection of health issues. Gamification fosters habit formation by leveraging feedback loops, while adaptive AI systems could soon tailor environments to individual cognitive states. However, rapid AI adoption demands caution to preserve critical thinking. Insights from evolutionary biology, such as bat-moth acoustic competition and spider web resonance, illustrate how organisms adapt perception to survive—paralleling human technological evolution. Ultimately, intentional use of technology can amplify human potential.
