Exploration science fiction assumed that space exploration technology would become cheaper, more effective, and privately available and it mostly didn't.
I mean, it did, but not in a way that led us to colonize other planets. We're still talking about getting back to the moon.
Cyberpunk assumed that computer technology would become cheaper, more effective, and privately available. And it did. And it led to a bunch of things that Cyberpunk didn't really predict.
Cyberpunk was right that there would be social repercussions from ubiquitous computing...
But lots of Cyberpunk stories assume wired networking, but we have 5g and WiFi. Lots of them assume portable computers slightly larger than laptops, while we have smartphones.
Their online communities look like Second Life (but successful,) not like Facebook groups.
Basically, Cyberpunk seems obsolete because we've leapfrogged it. Space Exploration never happened, so it still seems futuristic.
That's my guess, anyway. What do you think?
