> I've yet to see one startup which is America's answer to some chinese/indian startup. I hope that day comes soon.

What about Twitch, which makes its money from sponsorship and virtual gifts to streamers, a model pioneered in China and then Korea? Or the US esports leagues which copy, again Korea and China?

There are many technologies which appear later in the US but Americans think are indigenous (and the reverse as well -- I don't mean to pick on the US, simply responding to your comment). Consider chip cards (commonplace in Europe for 20+ years, still not well adopted in the US) or text messaging (adopted very late in the US).
