VCs are scared when they should be greedy
> In contrast with the scenario in 2000, most of today’s tech companies are real businesses.How many of today's startups are just servicing each other with VC money?  This isn't meant to be flippant - I'm genuinely curious (and while I bet it's a lot, I am skeptical it is overwhelming).I mean if we really look at some of the business models for these companies, they're clearly unsustainable.  Uber is a prime example of a company that seems destined to fail.  If your unit economics don't work then you're fucked, and even if you raise literally tens of billions of dollars you will eventually run out of money.  And yet companies like these are held up as prime examples of unicorn success stories.  It's not just Uber - there are serious problems with many of the most acclaimed startups.Obviously not all startups are terrible, but as someone who isn't a VC (but once considered becoming one), I think tech investors are unable to see their bias for just how awful most tech companies today are.
