Great explanation. IMO the GameStop phenomenon is the result of the combination of democratization of trading through software (Robinhood no fee trading, doing it on your cellphone) + social media enabled mass scale online community building (around some previously fringe niche). Any area that is subject to this kind of combination of change could face similar situation where the old institutions guarding the area would face increasing challenge from grass root efforts ("retards/autistics" as in wsb's lingo).
