United Earth

When shall we ever have a society much like the one featured in Star Trek Enterprise?

I'm assuming you mean TNG as TOS was all about cruising through the galaxy kicking alien butt.
Well, I'm happy to be the first to crush your dreams:
TNG features not only really, really crappy engineering (lol force fields everywhere) but also several magical plot devices made of phony physics that will NEVER become reality.
Rather use your time to think about what's going to happen once the word population hits the double digits.
