Supposing we didn't blow ourselves up, destroy the environment (and thus most of the planet) through rampant abuse of resources or get curbstomped by some alien force for trespassing with forbidden tech...
I fully expect to see:
- fully sentient robots, nigh indistinguishable from humans.
- cybernetics that perfectly replicate parts, even boosting natural abilities.
- medical science that can cure most major diseases without too much hassle.
- fusion power being a key energy source with solar and wind backups.
- a large space platform that people can live in.
- integrated electronics that allow man and machine to communicate even faster. (Like imagine playing a game where you control your digital avatar as if you moved your actual body.) Also that you can use to link up to the internet with.
But from all the new/amazing tech I also see problems.
- robots and cyborgs forced into prostitution.
- humans that have their integrated electronics hacked into.
- massive poverty, huge class gaps as some struggle to even survive while the ultra wealthy do nothing.
So basically pretty much like things are now just with even more extreme.
