As bubbles go, this one seems rather localized. Looking at that infographic, one can see than in the real estate and stock market sections most clearly. In the former, most of the gains went to certain select markets, mostly in coastal cities. In the latter, most of the gains went to the usual few suspects such as AMZN, FB, and GOOG.

It might follow that we might see localized bursting rather than a system-wide meltdown if this "bubble" pops.
