Maria Konnikova in The Atlantic:
The perfectibility of the human mind is a theme that has captured our imagination for centuries—the notion that, with the right tools, the right approach, the right attitude, we might become better, smarter versions of ourselves. We cling to myths like “the 10 percent brain”—which holds that the vast majority of our thinking power remains untapped—in part because we hope the minds of the future will be stronger than those of today. It’s as much a personal hope as a hope for civilization: If we’re already running at full capacity, we’re stuck, but what if we’re using only a small fraction of our potential? Well, then the sky’s the limit. But this dream has a dark side: The possibility of a dystopia where an individual’s fate is determined wholly by his or her access to cognition-enhancing technology. Where some ultra-elites are allowed to push the limits of human intelligence, while the less fortunate lose any chance of upward mobility. Where some Big Brother–like figure could gain control of our minds and decide how well we function.
What’s possible now, and what may one day be? In a series of conversations with neuroscientists and futurists, I glimpsed a vision of a world where cognitive enhancement is the norm. Here’s what that might look like, and how we can begin thinking about the implications.
