Uber was undercutting traditional taxis either through driver incentive or cheaper pricing. Many hot takes were around the sustainability of this business model without VC money. In many places this turned out to be true. Driver incentives are way down and Uber pricing is way up.

In a bubble the destruction is often that some big companies get destroyed and others survive. For every pets.com there is one Amazon. That doesn’t mean Amazon is good example to say naysayers during the dot bubble were wrong.
