Leaps in technology have not brought huge economic strides

A growing number of economists are wondering if the technological revolution has been greatly overhyped

But a funny thing happened on the way to the techno-revolution. We did not get a sustained return to rapid economic progress. Instead it was more of a one-time spurt which sputtered out about a decade ago

Remember Douglas Adams’s 1979 novel The Hitchhiker’s Guide to the Galaxy? It began with some technology snark, dismissing Earth as a planet whose life-forms “are so amazingly primitive that they still think digital watches are a pretty neat idea”. But that was then, in the early stages of the information technology revolution.

Since then we’ve moved on to much more significant things, so much so that the big technology idea of 2015, so far, is a digital watch. But this one tells you to stand up if you’ve been sitting too long!

Okay, I’m snarking too. But there is a real question here. Everyone knows that we live in an era of incredibly rapid technological change, which is changing everything. But what if what everyone knows is wrong? And I’m not being wildly contrarian here. A growing number of economists, looking at the data on productivity and incomes, are wondering if the technological revolution has been greatly overhyped – and some technologists share their concern.

We’ve been here before. The Hitchhiker’s Guide was published during the era of the “productivity paradox”, a two-decade-long period during which technology seemed to be advancing rapidly – personal computing, cellphones, local area networks and the early stages of the internet – yet economic growth was sluggish and incomes stagnant. Many hypotheses were advanced to explain that paradox, with the most popular probably being that inventing a technology and learning to use it effectively aren’t the same thing. Give it time, said economic historians, and computers will eventually deliver the goods (and services).

This optimism seemed vindicated when productivity growth finally took off circa 1995. Progress was back.

But a funny thing happened on the way to the techno-revolution. We did not, it turned out, get a sustained return to rapid economic progress. Instead, it was more of a one-time spurt, which sputtered out about a decade ago. Since then, we’ve been living in an era of iPhones and iPads and iDontKnows, but even if you adjust for the effects of financial crisis, growth and trends in income have reverted to the sluggishness that characterised the 1970s and 1980s. The whole digital era, spanning more than four decades, is looking like a disappointment. New technologies have yielded great headlines, but modest economic results. Why?

GDP of fun

Another possibility is that new technologies are more fun than fundamental. Peter Thiel, one of the founders of PayPal, famously remarked we wanted flying cars but got 140 characters instead. And he’s not alone in suggesting that information technology that excites the twittering classes may not be a big deal for the economy as a whole.

So what do I think is going on with technology? The answer is I don’t know – but neither does anyone else. What I’m pretty sure about, however, is that we ought to scale back the hype.

Writing and talking breathlessly about how technology changes everything might seem harmless, but, in practice, it acts as a distraction from more mundane issues – and an excuse for handling those issues badly. If you go back to the 1930s, you find influential people saying the same things such people say nowadays: this isn’t really about the business cycle, never mind debates about macroeconomic policy; it’s about radical technological change and a workforce that lacks skills for the new era.

And, thanks to the second World War, we finally got the demand boost we needed, and all those supposedly unqualified workers – not to mention Rosie the Riveter – turned out to be quite useful in the modern economy, if given a chance.

Of course, there I go, invoking history. Don’t I understand that everything is different now? Well, I understand why people like to say that. But that doesn’t make it true. – (New York Times service)
