Still waiting on technology to boom

Remember Douglas Adams’ 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!

OK, 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).

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 around a decade ago.

In other words, at this point, 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?

One possibility is that the numbers are missing the reality, especially the benefits of new products and services. I get a lot of pleasure from technology that lets me watch streamed performances by my favorite musicians, but that doesn’t get counted in GDP. The big productivity gains of the period from 1995 to 2005 came largely in things like inventory control, and showed up as much or more in nontechnology businesses like retail as in high-technology industries themselves. Nothing like that is happening now.

Another possibility is that new technologies are more fun than fundamental. Peter Thiel, one of the founders of PayPal, famously remarked that 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 that I don’t know – but neither does anyone else. Maybe my friends at Google are right, and Big Data will soon transform everything. Maybe 3-D printing will bring the information revolution into the material world. Or maybe we’re on track for another big meh.

What I’m pretty sure about, however, is that we ought to scale back the hype.
