Well, usually they aren’t. But you can’t say they actually don’t to everyone. People who are greedy will not get statisfaction out of materials, because they can never have enough. Some people may have a psyche problem (A mental injury, if you will) That may cause them to actually feel pleasure when they get more money. Certain types of people enjoy shopping just for the sake of it, and for them the fact that they have more items (and less money) is merely a side effect.
It is easy to watch what is fun, what is right and what is good from the perspective of a “normal” person; But you must also think about it from the perspective of people with mind “defects”, for we are all just a set of neurons.
For ex: If someone enjoys looking at their hands, is their fun less “good” than that of someone who enjoys playing video games?
If I gain happiness from having a bigger car (Not through impressing my friends, but simply by owning a better car) am I less good than you, who gets fun through owning different belief system?
And you will always think you are better than others, no matter what. Even when you think that everyone is equal, you think that you are better because you think that everyone is equal (Or through other beliefs)
Are there realy such things as feelings? If I make a computer that can respond to pain, will it be ethical to cause pain to it? the answer will probably be yes, because it can’t actually suffer, it can only know that it is hurt.
But if so, then what will happen if you put another computer up on the first, call the first one SC, and the second one conscious, and make the first interrupt the second’s action by sending it messages of pain, will it then be ethical to cause pain to it?
And what if it will have facial expressions?
And what if it will make the sound of a poor animal?
I belive the only difference batween a living being and a machine is the fact that we are somewhat based on primal survival mechanisms (SC) and partially based on rational thinking mechanism. This causes us to have much lack of logic, and is the only reason we can’t make an AI: We need to make something half random.
Well, guess that answers the OP initial question.
