"Hmm. A computer having an opinion"
A computer can already be programmed to have an opinion on a given topic, programming a computer to work out opinions is of course a little harder
"So that means that a computer can make an interpretation of happenings, a book, a painting and think about it? "
A computer can use algorithms to analyse a painting, or a book for that matter..........as for "thinking about it", when we "think" about stuff, all that happens is that we are aware (to a limited degree) of the inner workings of our brain.
"It can also think: I don't like that music?
It could be programmed to display signs of dislike when hearing certain types of music.
"And it is also possible that a computer creates a painting? A painting which expresses some feeling? "
There is already a robot painter in existance, the paintings are quite good, though of the abstract variety.
When you talk about expression of a feeling, of course things get more complicated, but on a basic level, AI can already alter the responce it gives depending on its "mood", which in turn depends on various external factors.
"So you think that it is possible that we can recreate the brain? Perhaps in a technological way, we will be able to recreate the brain. But in my opinion a person is not just a brain. A person also has a personality, built up through the years. This requires a lot of biological processes which I think we can't recreate. And if we are able to, then biological would turn out to be technology. Which implies that also evolution can be recreated"
A person IS just a brain, your personality, memories are all stored in your brain, your feelings, senses, everything is processes in your brain forming the person that you are. That much has been proven countless times, there are plenty of examples that show that people who have trauma to a particular part of the brain can get complete new personalities after the accident.
Biology isn't magic its just chemistry.
Consider this, if we could use a piece of silicon that had the same electrical and chemical properties of a cell, then we could build an artificial brain that would have the exact same properties as a biological brain.
Evolution can certainly be replicated, infact recently they have managed to get a computer to design circuits by using evolutionary principles.
