I don’t know that Uber will take down the to grocery store for $4, let alone get me anywhere useful like work. Probably someday, but not today, not in the eight years the author predicts, and probably not within my lifetime (middle-aged oldster here). I think the author’s mistake was applying iPhone timelines to cars. What the article says will happen, of that I am confident. But I think the author is off by an order of magnitude in many cases (like oil companies going out of business).
