Seeing many people pondering, Zhang Yuan added, "Many problems are simply unnecessary worries. Take sleep, for example. Humans need to sleep every day. During those hours, can it be said that the old me has died and a new me has been born?"
"And then take hibernation, where consciousness is directly interrupted for hundreds of years! When humans wake up, how does that consciousness reappear? Are the pre- and post-hibernation 'me' different?"
"...Even if that device is used, the original me is dead in an instant, creating a new me, but the new me has no feelings, no relevant memories... In the new me's cognition, consciousness still seems continuous, and that's already enough."
"If the 'new me' and the 'old me' are exactly the same, and the entire world hasn't changed at all, and no one knows about it, then, according to Occam's razor, there's no need to worry about such trivial matters."
Some scientists found this reasoning somewhat persuasive and nodded thoughtfully.
