Sci-fi doesn't have to have things "we can't do right now."
Brazil fits the classic sci-fi model of a throught-oppressing, bleak future, in which our basest natures are incorporated into industry and The System.
I wouldn't call 1984 sci fi either, but would call Brave New World sci fi. I think the sci in sci fi demands that there be something we are not currently capable of doing, beyond current knowledge, or technology. It is about more than just the future, but how humans react to technological progress. But, I recognize that it is not unreasonable to disagree with me.
