Agreed. Tesla is the unsung hero of the modern world if you ask me. The development of AC power, which we really owe to him, is the thing that made electricity an almost universal commodity. If Edison had been allowed to prevail, we would be using DC power which, because of the limited transmission distances, would have meant a lot of very expensive power generation stations all over the place. This would have made electricity so expensive so as to be only accessible to the wealthy or to industry.
Of course, maybe we would all be healthier now because in order to run our PCs at home, we would need to be pedaling a generator bike!
