Moritz joins other notable venture capitalists, such as Bill Gurley of Benchmark, in warning of valuation concerns in Silicon Valley.
While Moritz does believe that valuations are "very sporty" and that some unicorns will fail, he also adds that "a good number" of unicorns that will succeed.
Moritz also feels that while there will be a setback in Silicon Valley tech, he does not believe it will be as bad as the tech bubble bursting in 2000 because companies today are more sustainable.
