We won't need to go to a world before Uber since the business model is out there now. The core concept is great (and in fact it already pretty much existed in places with well-regulated taxi industries) and doesn't need a giant market cap or billions of dollars to operate, that's only needed for hubristic plans to reinvent transport that also don't need Uber to happen.

It's a bit like Tesla. Tesla has turned electric cars into something cool and edgy, but if it were to go under tomorrow it wouldn't even slow the pace of electric car adoption.
