Paul Krugman: Things to Celebrate, Like Dreams of Flying Cars

Merry Christmas!:

Things to Celebrate, Like Dreams of Flying Cars, By Paul Krugman, Commentary, NY Times: ...We’re still a very long way from space colonies and zero-gravity hotels, let alone galactic empires. But space technology is moving forward after decades of stagnation.

And to my amateur eye, this seems to be part of a broader trend, which is making me more hopeful for the future than I’ve been in a while.

You see, I got my Ph.D. in 1977, the year of the first Star Wars movie, which means that I have basically spent my whole professional life in an era of technological disappointment.

Until the 1970s, almost everyone believed that advancing technology would do in the future what it had done in the past: produce rapid, unmistakable improvement in just about every aspect of life. But it didn’t. ...

Now, there has been striking progress in our ability to process and transmit information. But while I like cat and concert videos as much as anyone, we’re still talking about a limited slice of life: ...

Over the past five or six years, however — or at least this is how it seems to me — technology has been getting physical again; once again, we’re making progress in the world of things, not just information. And that’s important.

Progress in rocketry is fun to watch, but the really big news is on energy, a field of truly immense disappointment until recently. ... The biggest effects so far have come from fracking, which has ended fears about peak oil and could, if properly regulated, be some help on climate change: Fracked gas is still fossil fuel, but burning it generates a lot less greenhouse emissions than burning coal. The bigger revolution looking forward, however, is in renewable energy, where costs of wind and especially solar have dropped incredibly fast.

Why does this matter? ... Well, you still hear claims, mostly from the right but also from a few people on the left, that we can’t take effective action on climate without bringing an end to economic growth. ...

But now we can see the shape of a sustainable, low-emission future quite clearly... Of course, it doesn’t have to happen. But if it doesn’t, the problem will be politics, not technology.

True, I’m still waiting for flying cars, not to mention hyperdrive. But we have made enough progress in the technology of things that saving the world has suddenly become much more plausible. And that’s reason to celebrate.
