The unicorn phenomenon is the result of hot money looking for any kind of return in a zombified financial system. 
Tech has had a good run the last ten years but things like QE have contributed to turning the sector into something of an asset bubble.

A few more rounds of QE and Twitter and LinkedIn might be back up in the clouds again.
