Given that it seems that to progress in any meaningful way it seems that we need more power to progress scientifically, I wonder if we are or have approached the next great "dark age" of technological progress due to the fear of the "nuclear" genie. Given what has happened in japan of recent, and the phasing out or planned phasing out of a lot of nuclear power I wonder if we are stalling ourselves technologically by fearing the power of nuclear. It seems to me that if we are to get off this planet and progress, we have to go nuclear of one form or another. Wether it be fission, fusion, matter/antimatter or whatever we have to progress to getting past the fear of "nuclear" and all associated technologies that have come from it and those that will come from it, or else we are doomed to waste decades and possibly centuries in a "dark age" merely progressing technologies incrementally rather then fundamentally. Although I'm sure other technologies like genetic engineering will progress, i believe we are fundamentally chaining ourselves where we are due to not wanting to take risks. Where would generations past be if they didn't sail there ships to australia or america because it was "too risky"? Someone might die? We seem to have lost our pioneering way as a society as a whole, and are too bogged down in risk managment and mitigation. Sure the loss of a human life is a tragedy, but should it also stop us progressing so that many more can be saved. Would madam Curie say dieing of radiation wasn't worth it if she came to this time and saw all the good xrays, and the like that came from the work she did? I seriously don't think so. So what are your thoughts?
