If there were robots talking and acting like humans, I would think they can love.
This is a natural reaction. Thats why Disney, for example, humanifies animals in their strips. Its what our brain tells us. That animals are somehow human underneath. Even if animals very likely have a different perspective than us, because of their limited mental abilities (compared to us).
Animals are a lot more like people than computers, though. Even the most simple animals can already feel, and they can already hurt.
I'm a programmer, but I cannot program the computer in front of me to feel anything, or to be hurt. It doesnt matter how much memory you give me or how fast you make this computer, it simply wont feel anything, ever.
Mind, I dont oppose that Momo would ACT like she would actually love Marigold. I oppose that there is actual feeling there.
Neurons can fire, not fire, send impulses to other neurons, and change their sensitivity to input. All their activity is some combination of the above. Can machines like us, built from neural networks, love?
http://en.wikipedia.org/wiki/Vitalism#Foundations_of_chemistry. Chemists used to believe there was some magic principle unique to organic molecules that made them different from inorganic molecules, and that they could never be synthesized from non-living ingredients.
I do not believe science has yet understood what consciousness is, and I doubt they ever will. Computers can emulate neuron networks, but that still wont give them the ability to feel, or to hurt.
Computers only have the ability to perform mathematical operations
From a similarly reductionist point of view, human beings only have the ability to perform chemical reactions. How can a collection of chemical reactions love? The existence of sociopathy suggests that, at least to some extent, the ability to love is a learned behaviour, or to put it another way, a matter of programming.
To my knowledge it is more a case of destroyed hardware than the lack of programming. If you disrupt the nerves of a human being or an animal, its possible you can cut off their arm or leg without them feeling anything. Likewise, sociopaths are unable to know consciously what they feel, or to understand other peoples feelings, because of destroyed parts of their brain. They are still able to hurt though.
My issue is simply the claim that was started as early as computers have been known, that somehow making computers faster and more powerful they would turn into something else. Just read or watch 2001 for that one and check out the abilities of HAL 9000. Its more obvious in the book, the movie stays kind of vague about this.
Yet computers did no such thing. They only became faster and better able to store things. They did not turn sentient and show no sign to turn sentient in the near or distant future. Its simply not there. No matter how fast it is, its still just a mathematical calculator.
