Neil deGrasse Tyson explores the idea of uploading consciousness with a mix of curiosity and skepticism. He questions whether simulating brain activity in a computer—neuron by neuron—would truly replicate you, or just create a copy that behaves like you. If your thoughts, memories, and personality are preserved digitally, is that still you or just a convincing echo?
Tyson leans toward the idea that consciousness may be inseparable from biology, and that even perfect simulations might lack the subjective experience—the “you” behind the eyes. It’s a philosophical puzzle: if your digital twin wakes up, who’s really in control?
