A mass drugging is how one young Saudi man in Riyadh described to me Mohammad Bin Salman’s Vision 2030, eight months after its ostentatious launch in April 2016. Smoke and mirrors, he meant.

But can he safely deliver more change to an already rapidly changing society? How much tinkering can one do with a fragile polity before it cracks under the pressure?
