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 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 robots are very rare among industrial accidents. However, in July 2015, a 57-year-old technician was killed by a robotic machine in an Ionia, Michigan, 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," crushing her 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 create 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 the impact of steam engines, Choset said: "Robots are just the next generation of tools."
Singer Aimee Mann, with help from actress Laura Linney, humorously depicted the danger of letting robots help you too much in this music video. And Choset was amused by a recent "Dilbert" strip about the boss' inability to stop a robot worker who decided to quit.
