I don't think people give this guy enough credit for his predictions. To take the side in defense of Edison... He was right that buildings would be fabricated from steel and other cheap materials; He was right that consumer goods would be fabricated from some cheaper material (but it's plastic); He was right that we'd have a library contained in a single book-like object (e.g. the Kindle); He was right that metals are all made of the same stuff (as is all matter); we haven't figured out how to convert them yet, though (and maybe it'll end up taking way too much energy; I'm no physicist). Basically, he predicted what kinds of things people would want that would also be technologically feasible; he just didn't correctly predict how they would become technologically feasible. (With the exception of gold-lined ships. That makes me wonder if the source of these predictions is all that trustworthy, because Edison clearly was no idiot.)
