Matt Ridley on the perpetual fretting that technological change will eliminate jobs and leave many permanently without work:
Bill Gates voiced a thought in a speech last week that is increasingly troubling America’s technical elite — that technology is about to make many, many people redundant. Advances in software, he said, will reduce demand for jobs, substituting robots for drivers, waiters or nurses.
The last time that I was in Silicon Valley I found the tech-heads fretting about this in direct proportion to their optimism about technology. That is to say, the more excited they are that the “singularity” is near — the moment when computers become so clever at making themselves even cleverer that the process accelerates to infinity — the more worried they are that there will be mass unemployment as a result.
This is by no means a new worry:
In the 1700s four in every five workers were employed on a farm. Thanks to tractors and combine harvesters, only one in fifty still works in farming, yet more people are at work than ever before. By 1850 the majority of jobs were in manufacturing. Today fewer than one in seven is. Yet Britain manufactures twice as much stuff by value as it did 60 years ago. In 1900 vast numbers of women worked in domestic service and were about to see their mangles and dusters mechanised. Yet more women have jobs than ever before.
Again and again technology has disrupted old work patterns and produced more, not less, work — usually at higher wages in more pleasant surroundings.
The followers of figures such as Ned Ludd, who smashed weaving looms, and Captain Swing, who smashed threshing machines (and, for that matter, Arthur Scargill) suffered unemployment and hardship in the short term but looked back later, or their children did, with horror at the sort of drudgery from which technology had delivered them.
Why should this next wave of technology be different? It’s partly that it is closer to home for the intelligentsia. Unkind jibe — there’s a sort of frisson running through the chatterati now that people they actually know might lose their jobs to machines, rather than the working class. Indeed, the jobs that look safest from robots are probably at the bottom of the educational heap: cooks, gardeners, maids. After many years’ work, Berkeley researchers have built a robot that can fold a towel — it takes 24 minutes.
Sad to see him go, but happy he’s at least getting a chance to play quarterback for another team. He was never going to be a franchise quarterback, but it’s difficult to say he ever really got a fair chance with the Vikings. As
