Of course, journalism remains trapped in a death cycle of click-chasing stupidity. This means that the triggering of the mechanism itself has now become a source of hype to propagate the panic ("OMGOMGOMG the market fell so fast that it tripped the circuit breakers!! Panic! Flee! Run away!"), so it's less clear that the mechanism is a net good.
