What worries you about the new world of artificial intelligence?
It is very often that the answer to this question resembles the plot of a science fiction thriller. People are concerned that the development of artificial intelligence produces "singularity": that point in history in which artificial intelligence will surpass human, which will provoke an unimaginable revolution in the life of man. People also wonder if, instead of controlling artificial intelligence, it will control us and make us, in effect, in cyborgs.
There are interesting topics to consider, but they are not pressing. They refer to situations that might not come until hundreds of years if any. At the moment, there is no known path among our best artificial intelligence tools (like the Google computer program that recently beat the world's best player in Go) and "general" artificial intelligence. Self-Aware software which can have to reason with common sense, acquire knowledge in many fields, feel, express and understand emotions, and so on.
