I have downvoted this, and all comments by both parties in the remainder of this conversation between Davorak and DanielLC. I would prefer to see fewer comments like these. Furthermore, you both seem to be incapable of resolving the disagreement, which requires actually understanding what the other guy is trying to say. And failing that, you seem incapable of ending the dispute which requires actually understanding that what you are doing is not working.
Even if one part has a good idea what the problem in communication is does not mean that that party automatically knows how to solve the problem or know weather or not they can solve it. The only way to find out sometimes is to try and see.
Reading your comment I get the impression you think the conversation was a hostile one. I did not have any hostile feels or thoughts taking part in that conversation. I did not get the impression that any were direct at me either.
Also it was in a discussion that was already hidden from the main discussion page so I had ...
It has been suggested that animals have less subjective experience than people. For example, it would be possible to have an animal that counts as half a human for the purposes of morality. This is an argument as to why that may be the case.
If you're moving away from Earth at 87% of the speed of light, time dilation would make it look like time on Earth is passing half as fast. From your point of reference, everyone will live twice as long. This obviously won't change the number of life years they live. You can't double the amount of good in the world just by moving at 87% the speed of light. It's possible that there's just a preferred point of reference, and everything is based on people's speed relative to that, but I doubt it.
No consider if their brains were slowed down a different way. Suppose you uploaded someone, and made the simulation run at half speed. Would they experience a life twice as long? This seems to be just slowing it down a different way. I doubt it would change the total amount experienced.
If that's true, it means that sentience isn't something you either have or don't have. There can be varying amounts of it. Also, someone whose brain has been slowed down would be less intelligent by most measures, so this is some evidence that subjective experience correlates with intelligence.
Edit: replaced "sentience" with the more accurate "subjective experience".
