Sad thing is humans continue to do the same things century on century. The only sweet spot to be is just as something is coming up (back) and before it peaks. Then retire and horde the lucre as long as possible (invest some, horde the rest... until the off-spring blow it 25 years later, while becoming decadent degenerates, a usual outcome though not the only one).
One thing humans do that no other creature on the planet does (at least not the same way) is TALK and HISTORY. Nothing new under the sun is anything more than a better way to do something we do from birth: talk, learn and remember, ambulate, fight/survive, procreate.
About the only thing we haven't done yet is build something better than "us", though Hawking recently warned AI would be the end of the human race... and even then Hawking was late by near five decades since DF Jones predicted that in 1966. (Colossus, the film version was The Forbin Project 1970)
Communication. IE. talking, seeing, entertaining (we do that, no other creature does) and each new step in technology is just doing it better or bigger, or over longer distances to larger audiences.
That same list OP linked to would apply to the difference between clay tablets, writing on papyrus (paper, hand writing), printing press, newspapers, books, ebooks... all the same. Though the technology did change the end result has not. So expect more of the same in the next gen (whatever that might be).
Facebook is the koffee klatch around the kitchen table. Google is the Card Index (librarian). Cell Phones are "chatting the neighbor" without standing at a fence. Nothing new. Just a different way of doing the same thing.
If you want to make big bucks, find a better way to do what humans want: talk, share, emote, see, hear, do, move about from one place to another. Do that and money will come... and you will be the Next Big Thing.
