Economists Say Newest AI Technology Destroys More Jobs Than It Creates 688

HughPickens.com writes: Claire Cain Miller notes at the NY Times that economists long argued that, just as buggy-makers gave way to car factories, technology used to create as many jobs as it destroyed. But now there is deep uncertainty about whether the pattern will continue, as two trends are interacting. First, artificial intelligence has become vastly more sophisticated in a short time, with machines now able to learn, not just follow programmed instructions, and to respond to human language and movement. At the same time, the American work force has gained skills at a slower rate than in the past — and at a slower rate than in many other countries. Self-driving vehicles are an example of the crosscurrents. Autonomous cars could put truck and taxi drivers out of work — or they could enable drivers to be more productive during the time they used to spend driving, which could earn them more money. But for the happier outcome to happen, the drivers would need the skills to do new types of jobs.

When the University of Chicago asked a panel of leading economists about automation, 76 percent agreed that it had not historically decreased employment. But when asked about the more recent past, they were less sanguine. About 33 percent said technology was a central reason that median wages had been stagnant over the past decade, 20 percent said it was not and 29 percent were unsure. Perhaps the most worrisome development is how poorly the job market is already functioning for many workers. More than 16 percent of men between the ages of 25 and 54 are not working, up from 5 percent in the late 1960s; 30 percent of women in this age group are not working, up from 25 percent in the late 1990s. For those who are working, wage growth has been weak, while corporate profits have surged. "We're going to enter a world in which there's more wealth and less need to work," says Erik Brynjolfsson. "That should be good news. But if we just put it on autopilot, there's no guarantee this will work out."

Researchers Accidentally Discover How To Turn Off Skin Aging Gene 175

BarbaraHudson sends this excerpt from The Province: While exploring the effects of the protein-degrading enzyme Granzyme B on blood vessels during heart attacks, professor David Granville and other researchers at the University of British Columbia couldn't help noticing that mice engineered to lack the enzyme had beautiful skin at the end of the experiment, while normal mice showed signs of age. The discovery pushed Granville's research in an unexpected new direction.

The researchers built a mechanized rodent tanning salon and exposed mice engineered to lack the enzyme and normal mice to UV light three times a week for 20 weeks, enough to cause redness, but not to burn. At the end of the experiment, the engineered mice still had smooth, unblemished skin, while the normal mice were deeply wrinkled.

Granzyme B breaks down proteins and interferes with the organization and the integrity of collagen, dismantling the scaffolding — or extra-cellular matrix — that cells bind to. This causes structural weakness, leading to wrinkles. Sunlight appears to increase levels of the enzyme and accelerate its damaging effects.

~ What do you think professor? Does it prove the existence of dark matter?

~ This? Oh, bless your heart, no, my young assistant. This is just chatter from some ancient interstellar civilization. Trade negotiations if I'm not mistaken.

~ Gosh, you're right, professor, I should have realized that myself.

~ Yes, completely useless I'm afraid. Fear not, we'll find the evidence someday.

Which could be a problem as they are given greater and greater direct responsibilities. Know how in a bureaucracy they can't fire you for exactingly following the rules and doing your job too well? Then this results in something stupid and/or tragic occurring, and that's when people scream "What were they thinking? What happened to simple common sense?" Well, AIs won't have that.

I'm hearing lots of carping, but not a lot of citerefs of SF stories set in the far future that do honestly depict the impact advanced technology would have on society, culture, etc. at least in a way Mr. Stross would expect it to. Any /.ers have any in mind?
