RICHARD FERNANDEZ: OUR FRAGILE WORLD: “Megacities are immensely fragile because complexity is only prevented from descending into chaos by the order provided by massive quantities of energy. The power outage in Manhattan is a reminder that civilization cannot function for more than a few hours without electricity. What will happen in a 5G, Internet of Things world if the whole mind bogglingly complex edifice rests on the tottering, variable and fragile basis of Green Power? In such a civilization a hundred percent uptime would be a hard requirement for many systems.”
