He takes forever to make his point so courtesy of Kagi's summarizer:

• The "Limitless" movie popularized the idea of taking a "magic pill" to enhance brain function, leading to increased interest in nootropics.
• The claim that humans only use 10-20% of their brain is a myth not supported by scientific evidence.
• Many people have tried to find real-life "Limitless" pills, leading to the rise of the r/nootropics subreddit where people experiment with unregulated supplements.
• The term "nootropic" is vague and can refer to any substance claimed to enhance mental abilities, even if there is little evidence to support those claims.
• Most nootropic supplements do not actually work as advertised, and some may even contain undisclosed, potentially dangerous ingredients.
• The U.S. supplement industry is largely unregulated, allowing companies to make unsupported claims about their products.
• Trying to "hack" your brain through supplements can become an unhealthy obsession, distracting from more effective ways to improve cognitive function.
• True productivity and self-improvement comes from living a balanced life, not from taking magic pills.
• Accepting one's own human limitations and imperfections is an important part of personal growth.
• Rather than chasing unproven supplements, it's better to focus on proven methods like exercise, healthy eating, and engaging in meaningful activities.
