Even as a supporter of the simulation hypthesis, I find it a bit troubling that there is no critical arguements on this site. I will try to make some.
Emotion. Feeling. The things in your stomache. The things that can drive you mad. Can that be computerized. Made into code? Love? Hate?
I think about that alot. And it is perhaps the weakest link in this hypothesis.
Can we do it now? Most certainly not. Or atleast I don't think so. Is it possible to create such an advanced code, that it immitates feelings? I don't know. I can't see how.
One feeling is also pain. It can drive you mad. Like the place that hurts is possesing your brain. You are helpless. Pain is so dominant, that you can even forget breathing.
Can pain be simulated? I don't know.
Being in love. A possesion of your mind. The person of your affection is beyond perfect. Godlike. You feel intoxicated by the presence of her/him. Can that be coded? I don't know.
So we can agree that feelings and pain are doubtful things to be able to code. But we don't know. Yet. The future might show.
If there is no positive advance in this field of coding AI's, it might tell us, that our universe is real. Dispite all the facts.
