That's a lot less reflective of UBER and more reflective of the type of startups SV is trying to take public. Look at any other SV Unicorn that IPO'd...take Twitter that IPO'd in 2013, it turned a profit one year since going public.
Twitter isn't really a shining example of success either - their share price has been sideways for 6 years.
Market cap is not and has never been a good proxy for success.
I do find it amusing that I was called out on this, though, since in the past I've been called out for not including SF as part of SV.
That's less growth than Comcast has had over the same period. Which most would not consider a dynamic incredible stock.
Their true value is their logistics software. If they would lease/sell that to other industries they would be rich beyond belief.
