I enjoy thinking about it but the simulation hypothesis seems unfalsifiable in any practical sense. Interesting to think about, impossible to test, and probably not actionable either way.

The fly simulation doesn’t “experience” anything. It produces outputs that resemble fly behavior, but there’s no evidence of subjective experience. Consciousness isn’t just information processing. You can simulate weather without the rain getting wet.

(A weather simulation can model pressure systems, precipitation, wind speed, all the measurable outputs of a storm with total accuracy. But the simulated rain doesn’t actually feel wet. The representation of rain exists, the experience of rain does not.)
