Your brain simulates 'you' as pure information, like a program
ctjlewis · x · 2026-10-06
The author argues that what your brain really simulates is neither your body nor the brain itself, but 'you' — the unified experience and person. That entity can't be seen or touched; it's like a computer program that must be simulated by some physical system without itself being physical. In a follow-up, he uses an analogy with numbers: holding up two fingers can 'simulate' the number two, but no one can produce the 'real' number 2 — numbers are pure information that can only be simulated.
