Hehe, well, AI has been a hot topic always in the computing area, and also "thanks" to the numerous scientific movies, now people are treating AI enabled robots as our killer or whatever things that might do harm to us human being... Unfortunately, I think that day, is possible in some sense, but yet gets a long way to go.... I remember it was described as almost impossible for us to create a machine with intelligence equivalent to a 10-years old boy. We are surely able to make machines with specialized AI, but it is absolutely not that simple to build a machine even close to we human. Well, hopefully interesting things take places with the help of grid computing...
