As Gibson himself has said, science fiction is a commentary on the moment in which it's written, and almost never succeeds in predicting the future. That doesn't mean it can't help shape the future (which I think Neuromancer did, at least a little). But that's a different thing.
The fun thing is I read the Sprawl and Bridge trilogies over the past year and oh my effing my how extremely accurate some of his extrapolations turned out to be. So rare and unusual, but post-2016 could not have turned out much different I guess
