it is in a sense derivation once removed.
That's a nice way to say "doubly derivative".
I would never steal an idea even if it was just slightly similar.
Then you'll probably never publish anything.
To me, it's like
Star Wars -
not qualitatively, but in the sense that people yell about how it's stolen but it's stolen in a generic fairy tale sense or generic cyberpunk furniture sense. It's not quite to the point of T2 which is stolen directly from a van Vogt story. But, with all three movies, while I'm with MC on the stealing is bayud, m'kay (see, I just stole something - ironic, huh?) I still say they're all cool movies. If someone brings a lawsuit and they win then they get paid. If not, it's all good. No, it's not the way to do things and they should credit and pay up front but sometimes even the creators (thieves) don't know where it's all coming from. "There's nothing new under the sun" and everything's all stolen from Homer anyway. So just enjoy the show and let the makers' consciences and the legal system take care of the rest unless you feel compelled to take it upon yourself to boycott the movie personally. But the derivative-ness is not itself a sign of goodness or badness as a movie.
I might add that Apple computers are superior not because of the surface and style, but because they work a million times better than PCs.
I was going to let this go
but it occurs to me that it's a great opportunity to link to one of my favorite pieces of writing on the subject by probably the biggest
second generation cyberpunk (even though I don't seem to like the guy's fiction or some of the ultimate thrust of this piece). I drive a proletarian po' folks PC but it's the tank version. Stephenson is an ex-Apple guy (at least at the time of this writing, long long ago in 1999 - exactly halfway back to
Neuromancer).

To update that, these days, Macs run with the free BSD under the hood and Mac users are paying zillions of bucks for commodity hardware, a GUI, and marketing. BSD is derived from genuine Unix code historically, but has rewritten it all (doubly derivative) while Linux is coded from scratch to be another Unix work-alike but they're both free, open source *nix. In Apple, BSD is the Apple and "the Mac" is just the candy covering.
(I'm sort of kidding - I mean, I don't like Macs or Windows but I don't like Linux either - I just dislike it by far the least. And I'm not a holy warrior, though I'll happily nudge folks into trying Linux if they want. But if Macs or Windows make you happy, we're all happy. It's a cool article, though, regardless.)
