The author argues Uber's two-sided platform and user base make it the natural aggregator for incremental autonomous-vehicle capacity, analogous to Booking.com for travel providers. He contends no single AV operator can saturate a city alone due to peak/slow hour economics, so an aggregator is structurally needed and Uber already occupies that position. The thesis is that Uber can now monetize this built platform 'like the railroads'; no specific catalyst or time horizon is given, and no explicit risk is stated.
