Earth by David Brin and Ender’s Game made some predictions in this area

Also William Gibson and other cyberpunk franchises. A big recurring theme is the lost fight against corporate interests. A bit worse than the state our world is in right now but certainly where we're heading.

I vaguely remember “The Nets” in Enders game but not how they functioned. What about Card’s portrayal did you find prescient?

Card's idea that everyone could publish and excellent voices would be amplified was correct in premise, though it's conclusion was completely off. Classic XKCD parodied it brilliantly IMHO: https://xkcd.com/635/
