"How many of the unicorn companies are really prosaic businesses - like limousine services or renting rooms in your house? The original VC firms from the '70's made their money and established the reputation of their respective brands by leveraging big cleverness with small capital, not small cleverness with big capital, and that's what's going on with these unicorns. That has never worked and it won't work this time. It doesn't produce venture quality returns, and it never will."
