There's a long article in this week's The Economist:
The onrushing wave
discussing the effect of changing technology upon the amount of employment available in different sectors of the economy.
Sample paragraph from it:
The case for a highly disruptive period of economic growth is made by Erik Brynjolfsson and Andrew McAfee, professors at MIT, in “The Second Machine Age”, a book to be published later this month. Like the first great era of industrialisation, they argue, it should deliver enormous benefits—but not without a period of disorienting and uncomfortable change. Their argument rests on an underappreciated aspect of the exponential growth in chip processing speed, memory capacity and other computer metrics: that the amount of progress computers will make in the next few years is always equal to the progress they have made since the very beginning. Mr Brynjolfsson and Mr McAfee reckon that the main bottleneck on innovation is the time it takes society to sort through the many combinations and permutations of new technologies and business models.
(There's a summary online of their previous book: Race Against The Machine: How the Digital Revolution is Accelerating Innovation, Driving Productivity, and Irreversibly Transforming Employment and the Economy)
What do people think are society's practical options for coping with this change?
To elaborate on this point, consider that the aggregate market cap of Apple, Microsoft, Google, Oracle, Intel, Qualcomm, Cisco, and Facebook is about 1.5e12 dollars. Conservative estimates for the cost of the US war on terror since 2001 is about the same. It's not an exact comparison, but it's an order of magnitude sanity check on my claim that wealth increase due to technological advance is on the same order of magnitude as wealth decrease due to institutional failure.
Market cap only represents the value those tech companies have managed to capture, though. I rarely click on Google's ads and therefore contribute little to their market cap, but access to search engines like Google has had a tremendous impact on my life.
