The Onrushing Wave

Douglas_Reay

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?

I asked mostly because I wanted a concrete reference point for the claim you were making; it's easier to avoid talking past each other that way.

So, the last 20-25 years of technological development accounts for 5% of Hong Kong's current wealth? Sure, that seems plausible enough.

What sorts of numbers do you think the people who talk about the enormous benefits technology delivers have in mind for that question?

Well, the snippet from the article compares current technological advances to the first era of industrialisation, so they're probably thinking 100-200% range.
