I think I was lucky to be a little older when I became famous. But still, the shock of the world starting to treat you in a weird way... I had come from the army, where we had to deal with life or death, and suddenly, people were asking whether you were cool or not. I have never cared about whether I'm cool.
The weird thing about the subway is no one looks at each other. So I play the O2 in London. It's a 20,000 capacity venue, and then I'll take the subway to my gig, and everyone's going to my gig, and no one looks at you. If anyone does, they say, 'Hey, you look exactly like James Blunt, only smaller.'
I am a troll. And do you know what? I really don't like social media apart from that aspect of it. Posting pictures of me doing this or that is really boring, but I enjoy engaging with people. I tell them it's just a laugh and to stay in touch if you're getting any grief. They're just opinions.
Viewed from a distance, or through the eye of the All-Knowing CEO of the Universe, the crash of 2008 followed the usual pattern. A long-lived boom driven by cheap credit, going back as far as 1982 (though subject to interruptions in the mid-1980s and 1990s, and in 2001), came to grief because of a rise in the cost of borrowing money.
For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.
There are signs that the age of petroleum has passed its zenith. Adjusted for inflation, a barrel of crude oil now sells for three times its long-run average. The large western oil companies, which cartellised the industry for much of the 20th century, are now selling more oil than they find, and are thus in the throes of liquidation.
The use of refined petroleum as fuel, which began in the 1850s, freed hundreds of millions of people from the toil of centuries, gave hundreds of millions more a life of ease and plenty, and, by allowing great cities to feed themselves from every corner of the world, multiplied the population of the earth fivefold.
For all their current prestige, Osama bin Laden and the suicide bombers are still regarded in all but the most desperate districts of Gaza or Peshawar as romantics with little chance of more than symbolic victories, however bloody and brutal. That gives both the Middle East and the West a small and distant hope of security.
Nature is not simply a technical or economical resource, and human beings are not mere numbers. To suggest that one can somehow align all the squabbling institutions of science, environmental management, government and diplomacy in an alliance of convenience to regulate the global climate seems to me optimistic.
