It's far more likely we're about to witness a significant new housing bubble courtesy of the Fed moving to negative interest rates. The tech bust is a joke compared to the size of the housing market, there's no "spreading" that can possibly go on from the tiny unicorn bubble to housing that is going to matter. Housing is $30 trillion, the unicorn bubble is the size of one Facebook (1% the size).
