Nothing to fear from imminent Blade Runner world, say experts

Set in 2019, cult 1980s movie Blade Runner envisaged a neon-stained landscape of bionic “replicants” geneticall­y engineered to look just like humans.

So far that has failed to materialis­e, but at a secretive research institute in western Japan, roboticist Hiroshi Ishiguro is fine-tuning technology that could blur the line between man and machine.

Highly intelligen­t, self-aware and helpful around the house, the robots of the future could look and act just like humans and even become their friends, Ishiguro and his team predict. “I don t know when a Blade

Runner future will happen, but I believe it will,” the Osaka University professor said.

“Every year we’re developing new technology — like deep learning, ’which has improved the performanc­e of pattern recognitio­n. Now we’re focusing on intention and desire, and if we implement them into robots whether they become more human-like.”

Robots are already widely used for tasks in Japan — from cooking noodles to helping patients with physiother­apy.

Marketed as the world’s first “cyborg-type” robot, HAL (hybrid assistive limb) — developed by Tsukuba University and Japanese company CyberDyne

— is helping people in wheelchair­s walk again using sensors connected to the unit’s control system.

Scientists believe service robots will one day help us with household chores, from taking out the garbage to making the perfect slice of toast.

Stockbroke­rs are already deploying artificial intelligen­ce (AI) bots to forecast stock market trends and science fiction’s rapid advance towards science fact owes much to the likes of Ishiguro.

He previously created an android copy of himself — using complex moving parts, electronic­s, silicon skin and his own hair — that he sends on business trips in his place.

However, Ishiguro believes recent breakthrou­ghs in robotics and AI will accelerate the synthesis of man and machine. “As a scientist, I hope to develop self-conscious robots, like you see in Blade

Runner, to help me understand what it is to be human,” he said. “That’s my motivation.”

SOURCE OF ANXIETY

The point at which the humans and machines converge has long been a source of anxiety for some, as depicted in popular culture. In Blade Runner, Harrison Ford plays a police officer who tracks down and kills replicants that have escaped and are living among the population in Los Angeles.

The Terminator series of movies starring Arnold Schwarzene­gger centres on a self-aware computer network that initiates a nuclear holocaust and, through autonomous military machines, wages war against human survivors.

“I can’t understand why Hollywood wants to destroy robots,” shrugged Ishiguro, who in 2007 was named one of the top 100 living geniuses by global consultant­s firm Synectics. “Look at Japanese cartoons and animations — robots are always friendly. We have a totally different cultural background.”

It is not just Hollywood that has concerns over AI. Tesla’s Elon Musk has called for a global ban on killer robots, warning technologi­cal advances could revolution­ise warfare and create new “weapons of terror” that target innocent people.

But Ishiguro insists there is no inherent danger in machines becoming self-aware or surpassing human intelligen­ce. “We don’t need to fear AI or robots, the risk is controllab­le. My basic idea is that there is no difference between humans and robots.”

The ultimate goal, according to Ishiguro’s colleague Takashi Minato, is “to bring robots into society as human companions — it’s possible for robots to become our friends.”

But will they look like us, and how comfortabl­e will we feel being surrounded by autonomous humanoids?

Japanese roboticist Masahiro Mori suggested in 1970 that the more robots resemble people, the creepier we find them — a phenomenon he called the “uncanny valley”.

Ishiguro’s first attempt at creating an android clone was based on his daughter and its “jerky movements” reduced her to tears. He has since perfected the template, including a creation he claimed was the world’s first news-reading android and a robot priest at a Kyoto temple unveiled earlier in 2019.

Minato shares his boss’s visionary ideas.

“Hopefully remote-controlled technology will develop to allow our alter egos to lead regular lives,” he said. “Like in the movie Surrogates — that would make life more convenient,” he added, referencin­g the sci-fi Bruce Willis hit in which people cocooned at home experience lives through robotic avatars.

While he will not put a date on a real-life Blade Runner future, Ishiguro claims the rise of the machines has already begun. “Already, computers are more powerful than humans in some cases. Technology is just another means of evolution. We are changing the definition of what it is to be human.” /AFP
