Ender's Game (1985) has a ton of spot on predictions of the future, if you haven't read that you might enjoy it (and the story and later universe are fascinating as well, with twists and turns, and the "two threads" storylines, where you can read the same events from two different characters in the plurilogies of books)

Some predictions in the first book:

- touch-screens in general and tablets in particular

- use of AI to adapt difficulty levels in games

- use of AI and virtual simulations for military training

- the Internet, and more specifically:

- the wide usage of forums, blogs, etc. (lots of references that kinda seem like social media, with propaganda spread, message control, etc.)

- the usage of sock-puppet accounts to influence elections and general political discourse (and the creation of "influencers" out of ... thin air)

Later in the series we also get:

- Cryptocurrencies

- AIs in control of financial systems
