I know there is no scientific evidence of a spirit or soul inside a person. But, given that most world religions teach that every person has a spirit/soul which is somehow connected to your identity/consciousness, I think it will be really interesting to see if any of these thought experiments do (or don't) actually happen experimentally. What does it mean for religion if conscious AI emerges, or someone has half of their brain implanted into a second body, and both bodies are conscious entities that think they are the original? What does it mean for religion if even in 1000 years conscious AI never emerges, and if it's impossible to get two halves of a brain to "wake up" in two different bodies?
