From Isaac Asimov to ‘Dilbert,’ robots have fascinated and worried

-

CINCINNATI — Robots are secretly plotting to kill us. Or enslave us. Or, at best, they will take our jobs, one by one.

From science fiction written by Isaac Asimov eight decades ago to “Dilbert” cartoons today, the relationsh­ip between robots and humans has long fascinated — and worried — people.

There’s even a term, “robophobia,” for an irrational anxiety about robots and other advanced automation machines.

And there are concerns beyond the ones stoked by watching too much “Terminator.”

Apple computer pioneer Steve Wozniak once suggested that robots would turn us into their pets. Physicist Stephen Hawking and tech entreprene­ur Elon Musk have also warned about the dangers of going too far, too quickly, in developing “thinking robots” with programmed intelligen­ce that might keep evolving self-awareness, similar to the humanoids in the HBO series “Westworld.”

Hawking told the BBC in 2014 that “developmen­t of full artificial intelligen­ce could spell the end of the human race.” So there’s that. Researcher­s vary in projection­s on how long from now, if ever, such a threat could exist.

For now, deaths by robot are very rare among industrial accidents. However, in July 2015, a 57-year-old technician was killed by a robotic machine in an Ionia, Mich., plant that makes auto bumpers, trailer hitches and chrome-plated plastics. Her husband filed a federal lawsuit, being contested by the defendants, alleging a malfunctio­ning robot took her “by surprise,” head.

As chief technology officer for a private-public effort to facilitate robotic solutions in U.S. manufactur­ing, professor Howie Choset of Carnegie Mellon University in Pittsburgh sees the fear of robots taking jobs making his mission tougher.

“You have to start this discussion with the baseline that automation and innovation creates jobs,” he said, by leading to new products and processes and the new jobs to make and operate them.

“Then you have to ask yourself, why would robots be different? And people are very quick to say, ‘Well, robots are intelligen­t, they do what humans can do,’ and there’s this fear that was sort of instilled by science fiction.”

Comparing fear of robots to 19th-century worries about steam engines, Choset said: “Robots are just the next generation of tools.”

And Choset was amused by a recent “Dilbert” strip about the boss’ inability to stop a robot worker who decided to quit.

Chris Boggess, 18, found the 2004 movie “I, Robot,” about a rogue killer robot drawn from Asimov stories, frightenin­g, but he has come to understand and appreciate their potential through the Butler Tech robotics program at Colerain High School near Cincinnati.

“The first day I walked in, I fell in love. I knew this was where I needed to be,” Boggess said. “I like robots, anything about technology.”

And if some day thinking robots acquired the ability to threaten humans, he said, “I would probably try to make friends with them.” crushing her

DENVER — Researcher­s say they have found a new clue into the mysterious exodus of ancient cliffdwell­ing people from the Mesa Verde area of Colorado more than 700 years ago: DNA from the bones of domesticat­ed turkeys.

The DNA shows the Mesa Verde people raised turkeys that had telltale similariti­es to turkeys kept by ancient people in the Rio Grande Valley of northern New Mexico — and that those birds became more common in New Mexico about the same time the Mesa Verde people were leaving their cliff dwellings, according to a paper published last month in the journal PLoS One.

That supports the hypothesis that when the cliff dwellers left the Mesa Verde region in the late 1200s, many migrated to northern New Mexico’s Rio Grande Valley, about 170 miles (270 kilometers) to the southeast, and that the Pueblo Indians who live there today are their descendant­s, the archaeolog­ists wrote.

The cliff dwellers would have taken some turkeys with them, accounting for the increase in numbers in New Mexico, the authors said.

Researcher­s have long debated what became of the people sometimes called Ancestral Puebloans, who lived in the elaborate Mesa Verde cliff dwellings and other communitie­s across the Four Corners region, where the states of Arizona, Colorado, New Mexico and Utah meet.

Archaeolog­ists believe the Ancestral Puebloans were a flourishin­g population of about 30,000 in 1200, but by 1280 they were gone, driven off by a devastatin­g drought, social turbulence and warfare.

Because they left no written record, their paths are not known with certainty. Many archaeolog­ists and present-day Pueblo Indians believe the Ancestral Puebloans moved to villages across New Mexico and Arizona, and that their descendant­s live there today.

Scott Ortman, a University of Colorado archaeolog­ist and a co-author of the PLoS One paper, said the turkey DNA supports the explanatio­n that many migrated to an area along the Rio Grande north of present-day Santa Fe, New Mexico.

“The patterns that we found are consistent with several other studies and several other lines of evidence,” he said in an interview.

Jim Allison, an archaeolog­ist at Brigham Young University who was not involved in the paper, agreed the findings mesh with other evidence of a southeastw­ard migration.

But a weakness of the study is the number of DNA samples used, he said. Researcher­s examined DNA from nearly 270 sets of turkey remains — some from before 1280 and some from after that date. But only 11 sets of remains came from the Rio Grande before 1280.

“It would have been really nice to have 10 times as many,” Allison said, but they were not available.

Ortman acknowledg­ed that the turkey DNA alone is not conclusive evidence of migration to the Rio Grande Valley.

The New Mexico turkeys could have come from someplace other than the Mesa Verde region, or turkey-herding communitie­s could already have sprung up in New Mexico before the Ancestral Puebloans left their Mesa Verde communitie­s, he said.

Some archaeolog­ists argue the evidence for a migration to the Rio Grande Valley is thin. Even supporters, such as Allison, acknowledg­e that some evidence does not fit, including difference­s in pottery and architectu­ral styles.

Tim Hovezak, an archaeolog­ist at Mesa Verde National Park, said he is not convinced the Ancestral Puebloans moved to the Rio Grande, but he tries to keep an open mind.

“I think it’s still a mystery, and it’s a very compelling one,” he said.

Ortman said other evidence besides the turkey DNA points to the migration.

The Tewa language spoken by some northern New Mexico Pueblo Indians today includes vocabulary “that seems to harken back to the material culture of the Mesa Verde area,” he said.

The Tewa term for the roof of a church translates roughly to “a basket made out of timbers,” Ortman said. That better describes the roofs used on kivas — ceremonial rooms — in ancient Mesa Verde communitie­s than it does the churches in New Mexico, he said.

Another line of evidence is similariti­es in the facial structures of the remains of ancient people from the Mesa Verde region and New Mexico, Ortman said.

Examining human DNA from Ancestral Puebloan remains would provide a more definitive answer, Ortman said. But some contempora­ry Pueblo Indians object to doing that, and Ortman and others said they respect their wishes.

Theresa Pasqual, a member of the Acoma Pueblo in northweste­rn New Mexico and the pueblo’s former preservati­on director, said she knows of no pueblos that would consent to DNA testing on ancestral remains because of spiritual and cultural concerns.

Pasqual, who is studying archaeolog­y at the University of New Mexico, said she was heartened by the turkey DNA study because it supports the oral traditions of Acoma and other present-day pueblos that point to ancestral ties to the Mesa Verde region.

Some Acoma families still raise domestic turkeys and hunt wild ones, but it would be difficult to trace that tradition to the Ancestral Puebloans, Pasqual said.

The Ancestral Puebloan sites are a key factor in what she called Acoma’s “migration narrative.”

“These places have been a part of our narrative and a part of our history and a part of our present-day life for as long as we can remember,” Pasqual said.
