And all ride sharing companies are copying Uber, which are copying taxis, who are copying a long chain of copied ideas with differences in execution

All ideas are copied, humans are incredibly bad at creating wholly new things, what we are good at is taking things we already know and combining them, often times new things come out.

Yes, but the amount of "China copies everyone else" that usually goes around deserves a rebalance. As someone actually active in the food space in Asia, my opinion is pretty informed on such matters. Anyway, business as usual SV pro-American echo chamber here. Sigh.
