I see what you’re saying, but I think sci-fi is in a bit of a different place there. Neuromancer is concerned with what’s coming. It’s not painting a 2000s of the 80s, it’s painting the future of a present.

Predestination is a bit different in that it’s a time travel story. In Neuromancer (or Blade Runner, for that matter) the technology is not about extrapolating technology, it’s about extrapolating society.

It’s not impossible for sci-fi to be coded to a time. I don’t think you could make Strange Days today, it’s so ingrained into the idea of the end of the millenium and the rise of the Internet. It’d be different even if you kept the setting. A nostalgic look back instead of an anxious look forward.

Neuromancer has the same problem, only on top of everything else it’s also just vaguely futuristic, so it’s not like the 80s look and feel is integral to the story (in case the endless rehashes of the stories for the past forty years hadn’t proven that).

We’ll see. The worst case scenario is we’re thinking this through more than the people making the actual thing.
