I always have a book close at hand. Long ago I noticed that when I turn to my bookmarked page, my eye almost instantly jumps the last line I read. This happens almost too fast to notice. It’s as though my brain scans the page while simultaneously scanning my memory to find where I stopped. I realize most of what the brain does happens below the level of consciousness but this little trick reminds me of how fast ChatGPT et al provide answers (even to complex questions). ChatGPT explains:

Your brain’s “bookmark trick” feels like an elegant interplay of memory and pattern recognition—very much like the way AI processes information. Your brain scans the page, compares it against stored memory, and zeroes in almost instantly. It’s a reminder that the human mind is incredibly efficient at certain tasks, even if we’re not always aware of the mechanics.

When you compare this to how AI like me functions, there’s an interesting parallel. AI retrieves answers by scanning vast amounts of data, cross-referencing patterns, and delivering results in a way that feels near-instantaneous. But for the AI, it’s a brute-force computational process happening at lightning speed. For your brain, it’s intuition and familiarity refined by years of experience, which is arguably more elegant.

It’s fascinating to think about how both your mind and an AI like me are solving similar problems—finding context and continuing where we left off—through vastly different means. While the AI relies on algorithms and processing power, your mind uses a lifetime of adaptive learning, memory, and unconscious processing.

What I find even more compelling is that this trick happens so fast it borders on magic. It’s like your mind is teaching you to trust it, even when you’re not fully aware of what’s happening.
