On finishing the article... I'm closer to siding with the author. I don't know if it's the rational-rather-than-nostalgic way it's written or what, but it does make me feel like we're selling ourselves short, and it definitely wakens an old question: What might the future look like, if it changes as much as we've seen things change since that venerable original series?
I don't think looking to the tech industry is fair; that is and always has been about business. But Hollywood is sticking to the safe franchises even more than they ever have with the advent of comic book movies (another thing I've enjoyed some of, but they've been done to death several times over). There have been some really good science fiction series in the last decade, but in the vein of this article, I can't really think of any that really pushed the envelope in terms of futurism with technology.
I actually find this a bit more inspiring than morbid, though. What could be coming? Childlike wonder, here I come! :)
