Brett Winton: @DowJonesAl @elonmusk @barronsonline @jackhough @profgalloway @garyblack00 @luminartech 公平地说，我也不确定优步。但事实是，打车市场已经变成了竞争性的双头垄断，而且有强有力的证据表明，自动驾驶出租车至少会以同样的方式集中注意力，如果不是更加集中的话。

But the fact is that the ride-hail market has whittled to a competitive duopoly, and there’s strong evidence that robotaxi would at least similarly if not more steeply concentrate.
