A mob of starving people advanced on the presidential palace chanting, “We want food”. They were met by soldiers and police dispatched by the tyrant from his lavish palace decorated opulently with a golden sun, giant rock crystal mirrors, sparkling chandeliers and towering oil portraits.

The scene wasn’t 19th century France, but 21st century Venezuela.

And if you are wondering why you haven’t seen it on the news, it’s because Venezuela is a Socialist disaster area that was once being used as a model by the left. Now it’s a place where the vast majority of people can’t afford basic food staples and a third are down to two or fewer meals a day.

Obama laughed and joked with deceased monster Hugo Chavez, who handed him a copy of the anti-American tract, “Open Veins of Latin America” that had even been disavowed by its own author. Obama called the book a “nice gesture,” but Eduardo Galeano, its author, had told an audience that the left “commits grave errors” when in power.

Venezuela, once a wealthy oil state, where the doctors offering “universal health care” have no medicine and starving people loot government stores looking for food, is yet another example. 50 people are dead in the latest food riots. Their graves are yet another “grave error” of the left.

Italy is preparing a €40bn rescue of its financial system as bank shares collapse on the Milan bourse and the powerful after-shocks of Brexit shake European markets.

An Italian government task force is watching events hour by hour, pledging all steps necessary to ensure the stability of the banks. “Italy will do everything necessary to reassure people,” said premier Matteo Renzi.

“This is the moment of truth we have all been waiting for a long time. We just didn’t know it would be Brexit that set the elephant loose,” said a top Italian banker.

The share price of banks crashed for a second trading day, with Intesa Sanpaolo off 12.5%, and falls of 12% for Banka MPS, 10.4% for Mediobana, and 8% for Unicredit. These lenders have lost a third of their value since Britain’s referendum five days ago.

“When Britain sneezes, Italy catches a cold. It is the weakest link in the European chain,” said Lorenzo Codogno, former director-general of the Italian treasury and now at LC Macro Advisors.

Islamic violence is nearly impossible to deny. But why is Islam violent?

The usual answer is to point to Koranic verses calling for the conquest and subjugation of non-Moslems. That certainly covers the theological basis for Islamic violence. But it fails to explain why Moslems continue to practice it. Even against each other. Violence has become the defining form of Islamic exceptionalism.

Islam made the standard tactics of tribal warfare far more effective. Its alliance was harder to fragment and its fighters were not afraid of death. But at the same time Islam remained fundamentally tribal.

It made tribal banditry more effective, but didn’t change the civilization. It codified the tribal suspicion of outsiders and women into a religious doctrine. That still drives Islamic violence against non-Moslems and women today.

And yet Islam could have reformed. All it had to do was choose a different civilizational strategy.  Why didn’t it?

India’s bid to become the ‘economic super-tiger’ of Asia is in serious doubt after an assault on the independence of the central bank and failure to deliver on promised reforms.

The country has been the darling of the emerging market universe since the Hindu nationalist Narendra Modi swept into power in May 2014 promising a blitz of Thatcherite reform and a bonfire of the diktats, but key changes have been blocked in the legislature. The government has turned increasingly populist.

Matters have come to a head with the de facto ouster of Raghuram Rajan, the superstar governor of the Reserve Bank of India (RBI), rebuked for keeping monetary policy too tight. It is part of a pattern of attacks on central banks by politicians across the world, and the latest sign that the glory days of the monetary overlords are waning.

“This is ‘Rexit' – India’s equivalent of ‘Brexit.  It looks very bad for India and will not go down well in financial markets. He was defeated by the crony capitalists up against him,” says Lord Desai from the London School of Economics.

Last week I visited an island and stood among a crowd of puffins. If I turned my head I could see the lighthouse. If I looked up, the arctic terns were above my head. Yet I never left my living room.  How come? I was wearing a virtual-reality mask.

I have tried this “Oculus” technology once before, when visiting Facebook in California (which owns Oculus) and it is truly extraordinary to have an all-round, up-and-down view of the world depending on how you turn your head. All it involves is a special (Samsung) smartphone jammed into a pair of goggles.

Is it the next wave of tech? I have no idea. Apart from games, virtual visits to inaccessible nature reserves and maybe estate agents, it may not have many practical applications. But I may be wrong. Does the next wave lie in big data? Or robotics? Or the internet of things? Or something else entirely?

Nobody knows. The one thing that the history of technology shows above all else is our complete inability to see what comes next.

Yet something will come next, of that we can be confident. By 2025 there will be a vast new firm, valued at an astronomical sum and run by people who look like teenagers from a futuristic building in . . . well, where will it be? Can you imagine it being in Europe? Me neither.  Here’s why.
