This very much. Ultimately what Uber (and most other gig economy companies) offers is on-demand servants - and there's a floor to how much this service can sustainably cost. The trick Uber pulled was inventing something that has a clear (and sustainable) market within the wealthy elite, but convincing investors that the product could be sustainably operated for vast swathes of the middle- and upper-middle class. In other words, the trick was asserting their TAM was way larger than reasonable measure, and having everyone believe it.
