As you know, technology has been improving unstoppably among the years. Now, machines and even robots are introduced. Now, this a little worries me. One, extremely destructive nuclear weapons are been made, and some day, powerful even enough to destroy the world, I bet. It's not safe, at all. One day, it's going to cause this world's downfall. Another things is machines, and robots, paticurly. It's not like I saw that movie, I Robot, but i'm wondering what would happen if humen make machines a little too smart, and they will overpower humen power and brains? Do you think technology should go on like this, until one day a crisis happens?
