You are focusing on the negative. Without Tesla's innovations, we'd probably be at least decades behind what we currently use. If he hadn't invented the AC motor, it is certainly possible that it would have taken much longer to develop and most likely DC would be much more prevalent today, which could have significantly increased costs of energy. Without the Tesla coil, radio would not have developed as quickly, so technology around communication (amongst other things) would probably not be as well-developed as it is today. He came up with the tiltrotor/tilt-wing concept used in helicopters as well as the earliest proposal for the use of turbine engines in rotor aircraft. So aviation would probably be set decades back without him. If he hadn't invented a radio-controlled boat and have shown it of to others, technology related to remote-control may not have developed as quickly. He believed that women would become the dominant sex in the future. I also think he is right about this. The man had hundreds of patents and was able to drive Edison almost into the ground, Edison's company basically having been the Google of its day. I for one am fascinated by Tesla. Without him, the world would have been much less interesting.
