In this post's title, "Ray" refers to Ray Kurzweil, my favorite techno-optimist and certainly the craziest. Ray is a "futurist" at Google.
The "singularity" is his most famous prediction about the future, but Ray's "unfettered" imagination is not constrained by reality in any way. Another wacko technophile, Peter Diamandis, lists some of Ray's more recent predictions about the next 25 years.
- By the late 2010s, glasses will beam images directly onto the retina. Ten terabytes of computing power (roughly the same as the human brain) will cost about $1,000.
- By the 2020s, most diseases will go away as nanobots become smarter than current medical technology. Normal human eating can be replaced by nanosystems. The Turing test begins to be passable. Self-driving cars begin to take over the roads, and people won’t be allowed to drive on highways.
- By the 2030s, virtual reality will begin to feel 100% real. We will be able to upload our mind (i.e., consciousness) by the end of the decade.
- By the 2040s, non-biological intelligence will be a billion times more capable than biological intelligence (a.k.a. us). Nanotech foglets will be able to make food out of thin air and create any object in [the] physical world at a whim.
- By 2045, we will multiply our intelligence a billionfold by linking wirelessly from our neocortex to a synthetic neocortex in the cloud.
Nanotech foglets? But hey, this is Great Stuff! If you're writing Science Fiction, that is.
Back in what I affectionately call "The Real World," actual technologists and researchers are trying to build smart robots. Unfortunately for Ray, that's not going so well.
I will quote excerpts from the recent New York Times piece Relax, The Terminator Is Far Away (May 25, 2015).
In glossy sci-fi movies like “Ex Machina” and “Chappie,” robots move with impressive — and frequently malevolent — dexterity. They appear to confirm the worst fears of prominent technologists and scientists like Elon Musk, Stephen Hawking and Bill Gates, who have all recently voiced alarm over the possible emergence of self-aware machines out to do harm to the human race.
“I don’t understand why some people are not concerned,” Mr. Gates said in an interview on Reddit.
“I think we should be very careful about artificial intelligence,” Mr. Musk said during an interview at M.I.T. “If I had to guess at what our biggest existential threat is, it’s probably that,” he added. He has also said that artificial intelligence would “summon the demon.”
And Mr. Hawking told the BBC that “the development of full artificial intelligence could spell the end of the human race.”
Not so fast. Next month, the Defense Advanced Research Projects Agency, a Pentagon research arm, will hold the final competition in its Robotics Challenge in Pomona, Calif. With $2 million in prize money for the robot that performs best in a series of rescue-oriented tasks in under an hour, the event will offer what engineers refer to as the “ground truth” — a reality check on the state of the art in the field of mobile robotics.
A preview of their work suggests that nobody needs to worry about a Terminator creating havoc anytime soon. Given a year and a half to improve their machines, the roboticists, who shared details about their work in interviews before the contest in June, appear to have made limited progress.
In the previous contest in Florida in December 2013, the robots, which were protected from falling by tethers, were glacially slow in accomplishing tasks such as opening doors and entering rooms, clearing debris, climbing ladders and driving through an obstacle course. (The robots had to be placed in the vehicles by human minders.)
Reporters who covered the event resorted to such analogies as “watching paint dry” and “watching grass grow.”
This year, the robots will have an hour to complete a set of eight tasks that would probably take a human less than 10 minutes. And the robots are likely to fail at many. This time they will compete without belays, so some falls may be inevitable. And they will still need help climbing into the driver’s seat of a rescue vehicle.
Twenty-five teams are expected to enter the competition. Most of their robots will be two-legged, but many will have four legs, several will have wheels, and one “transformer” is designed to roll on four legs or two. That robot, named Chimp by its designers at Carnegie Mellon University, will weigh 443 pounds.
None of the robots will be autonomous. Human operators will guide the machines via wireless networks that will occasionally slow to just a trickle of data, to simulate intermittent communications during a crisis. This will give an edge to machines that can act semi-autonomously, for example, automatically walking on uneven terrain or grabbing and turning a door handle to open a door.
But the machines will remain largely helpless without human supervisors.
“The extraordinary thing that has happened in the last five years is that we have seemed to make extraordrinary progress in machine perception,” said Gill Pratt, the Darpa program manager in charge of the Robotics Challenge. Pattern recognition hardware and software has made it possible for computers to make dramatic progress in computer vision and speech understanding.
In contrast, Dr. Pratt said, little headway has been made in “cognition,” the higher-level humanlike processes required for robot planning and true autonomy. As a result, both in the Darpa contest and in the field of robotics more broadly, there has been a re-emphasis on the idea of human-machine partnerships.
“It is extremely important to remember that the Darpa Robotics Challenge is about a team of humans and machines working together,” he said.
“Without the person, these machines could hardly do anything at all.”
In fact, the steep challenge in making progress toward mobile robots that can mimic human capabilities is causing robotics researchers worldwide to rethink their goals. Now, instead of trying to build completely autonomous robots, many researchers have begun to think instead of creating ensembles of humans and robots, an approach they describe as corobots or “cloud robotics.”
Ken Goldberg, a University of California, Berkeley, roboticist, has called on the computing world to drop its obsession with [the] singularity, the much-ballyhooed time when computers are predicted to surpass their human designers.
Rather, he has proposed a concept he calls “multiplicity,” with diverse groups of humans and machines solving problems through collaboration. For decades, artificial-intelligence researchers have noted that the simplest tasks for humans, such as reaching into a pocket to retrieve a quarter, are the most challenging for machines.
“The intuitive idea is that the more money you spend on a robot, the more autonomy you will be able to design into it,” said Rodney Brooks, an M.I.T. roboticist and co-founder two early companies, iRobot and Rethink Robotics. “The fact is actually the opposite is true: The cheaper the robot, the more autonomy it has.”
For example, iRobot’s Roomba robot is autonomous, but the vacuuming task it performs by wandering around rooms is extremely simple. By contrast, the company’s Packbot is more expensive, designed for defusing bombs, and must be teleoperated or controlled wirelessly by people...
You will know the "singularity" has arrived when humankind unleashes a ginormous army of nanobots which will take CO2 out of the air and bury it underground — one molecule at a time
Wow... this movie trailer is one of the dumbest things I've ever seen
