I am kind of disappointed. I was looking at this guys old blog about "the future" and it seems like most people there had a very optimistic perspective about what the 21st century was going to be like: Hover cars, lunar bases, underwater cities, virtual reality, holograms, food pills, Robots, Interplanetary Travel, and so on by the year 2000. Why did that vision of the future never happen? It seems the only science fiction technology that we have are computers and the internet and online games. Why did that future never come to be?
