In a world of rapidly accelerating change, from iPads to eBooks to genetic mapping to MagLev trains, we can't help but wonder if technology is our servant or our master, and whether it is taking us in a healthy direction as a society.* What forces drive the steady march of innovation?* How can we build environments in our schools, our businesses, and in our private lives that encourage the creation of new ideas--ideas that build on the new technology platforms in socially responsible ways?Kevin Kelly and Steven Johnson look at where technology is taking us. One of the co-founders of Wired Magazine, Kelly's new book, What Technology Wants, makes the argument that technology as a whole is not a jumble of wires and metal but a living, evolving organism that has its own unconscious needs and tendencies. Johnson's new book, Where Good Ideas Come From, explains why certain spaces, from 18th-century coffeehouses to the World Wide Web, have an uncanny talent for encouraging innovative thinking.

Economic meltdown, pro-democracy revolts, protest camps - it's kicking off everywhere. But was all this catalysed by new social media and technologies as many claimed? Paul Mason, a BBC correspondent who witnessed much of the unrest at first-hand, tells Liz Else that it's a lot subtler than that

A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the engineers who discovered it and proved that it works. The process, called 'photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

To know what the most important virtue of our age is we need to have at least a basic understanding of our age. Our era is becoming increasingly characterized by uncertainty. Fortunately or unfortunately, more than a cursory elucidation of our situation is beyond the scope of this essay. There are geopolitical, economic, technological and environmental trends worth mentioning. When the more philosophical portion of this  discourse arrives I will argue that the virtue of wisdom underlies the meaningfulness and efficacy of all other virtues, and this in broad strokes is primarily due to (1) the aforementioned instability in our surroundings ; (2) the relationship between the deontological and virtue; and (3) the nature of agency itself.  Whether uncertainty itself can provide an ethical foundation for us to elaborate on will be a separate question, and finally I speculate on where wisdom leads us in the context of a philosophy that is politically active and not doomed to irrelevance to and by the larger population.

In his thoughtful criticism of my essay on the future of fossil fuels and the poor prospects for renewable energy, Andrew Leonard characterizes my message as one that "we have nothing to worry about." This may be partly the fault of my presentation, because in the course of being provocative I did not make it sufficiently clear that I was engaged in analysis, not advocacy. I made the prediction that, even in the presence of global warming, the countries of the world are unlikely to allow the vast stores of fossil fuels in the earth's crust to lie there undisturbed, when technology is making many of them ever more accessible and cheaper than the renewable energy alternatives. For the record, I personally wish that greenhouse gas emissions would stop immediately, and I personally would prefer a world of harmonious international cooperation for all time. Neither of my personal preferences is going to be fulfilled and neither affects the accuracy of my analysis.

I've written before about the crisis of inequality in the United States and about the quasi-religious abhorrence of "wealth redistribution" that causes many Americans to oppose tax increases, even on the ultra rich. The conviction that taxation is intrinsically evil has achieved a sadomasochistic fervor in conservative circles-producing the Tea Party, their Republican zombies, and increasingly terrifying failures of governance. Happily, not all billionaires are content to hoard their money in silence. Earlier this week, Warren Buffett published an op-ed in the New York Times in which he criticized our current approach to raising revenue. As he has lamented many times before, he is taxed at a lower rate than his secretary is. Many conservatives pretend not to find this embarrassing. Conservatives view taxation as a species of theft-and to raise taxes, on anyone for any reason, is simply to steal more. Conservatives also believe that people become rich by creating value for others. Once rich, they cannot help but create more value by investing their wealth and spawning new jobs in the process. We should not punish our best and brightest for their success, and stealing their money is a form of punishment. Of course, this is just an economic cartoon. We don't have perfectly efficient markets, and many wealthy people don't create much in the way of value for others. In fact, as our recent financial crisis has shown, it is possible for a few people to become extraordinarily rich by wrecking the global economy. Nevertheless, the basic argument often holds: Many people have amassed fortunes because they (or their parent's, parent's, parents) created value. Steve Jobs resurrected Apple Computer and has since produced one gorgeous product after another. It isn't an accident that millions of us are happy to give him our money. But even in the ideal case, where obvious value has been created, how much wealth can one person be allowed to keep? A trillion doll

The danger of depending too much on a Chinese rescue for the global economy: Even planned slowdowns cause panic

Amid the silly videos and spam are the roots of a new reading and writing culture, says Clay Shirky.

Americans are poor and hungry. Maybe now is not the time to be cutting government funding for food stamps?

But aside from the sheer hysterical ludicrousness of criticizing someone for engaging in "criticism of business" in the year 2010, when we have more recent examples than we can possibly count of businesses behaving irresponsibly, recklessly and criminally in their single-minded pursuit of profit, Paul's basic stance is actually quite useful; it highlights a core weakness in libertarian theory: its lack of a robust mechanism to ensure that the natural environment is not devastated by the actions of businesses.

Will future megacities grow themselves, heal themselves and be at peace with their surrounding environment instead of in conflict with it? Yes. But only if only we decide to do it.
