Bertolt Meyer is used to being viewed as not fully human. Born with a stump where his left hand should have been, he spent his childhood wearing a hook connected to an elaborate pulley and harness.
“To open the hook and grasp things I had to flex my shoulders like this,” he said, striking a He-Man pose. “The harness was very uncomfortable. I was always sweating.”
Even when, at the age of 19, Meyer exchanged his body-powered hook for a myoelectric prosthesis with a more realistic plastic hand, he kept his disfigured left arm hidden from view.
“It wasn’t simply a question of aesthetics,” he said, proffering the plastic hand, now grubby and discolored with use. “You have to understand, this is a stigma. People think its weird. You walk around with a sense of shame.”
Today, that shame is gone. In 2009, Meyer, a social psychologist at the University of Zurich, was fitted with an i-limb, a state-of-the-art bionic prosthesis developed by a Scottish company, Touch Bionics, that comes with 24 different grip patterns. To select a new suite of gestures, Meyer simply taps an app on his iPhone.
“This is the first prosthesis where the aesthetics match the engineering,” he said, balancing a pen between his purring electronic fingers. “It’s part of me and I’m proud of it.”
Since appearing in the British Channel 4 documentary How to Build a Bionic Man, in which he allowed engineers to build a robotic replica of the rest of his body complete with artificial heart, lungs and an alarming prosthetic likeness of his face, Meyer has become something of a poster boy for “transhumanism.” Encompassing everything from robotic limbs to memory-enhancing neural implants to gene therapies that slow aging, transhumanism (or posthumanism) concerns the technologies and drugs that are rapidly altering the limits of human performance, as well as notions about what we might look like in future.
As Nick Bostrom, the head of the Future of Humanity Institute at the University of Oxford and a leading transhumanist thinker puts it, transhumanism “challenges the premise that the human condition is and will remain essentially unalterable.”
“It seems to me fairly obvious why one might have reason to desire to become a posthuman in the sense of having a greatly enhanced capacity to stay alive and healthy,” he writes. “I suspect that the majority of humankind already has such a desire implicitly.”
However, while some medical interventions such as organ transplants command wide social acceptance, others invite moral approbation. This is particularly the case where the enhancement is regarded as a vanity or may be detrimental to health.
Then there is the question of access — an i-limb costs £30,000 (US$47,160), while an artificial heart will set you back £70,000 — and whether it is OK to turn a blind eye to the “off-label” use of drugs such as Ritalin, which was developed as a treatment for attention deficit hyperactivity disorder, but is increasingly being used to enhance cognitive performance.
Even more ethically fraught is the line between restorative therapy and elective surgery. Last year, for instance, an Austrian man who damaged his hand in a motorcycle accident opted for an amputation and had a bionic replacement fitted.
At the moment, bionic hands are poor substitutes for the real thing — they can grasp and manipulate objects, but they cannot feel. Yet what if, in the future, we could make bionic hands with a sense of touch that were also capable of enhanced performance? Would we be happy if a struggling concert pianist elected to amputate his hand so that he could perform Rachmaninoff’s infamously difficult third concerto?
For the moment, the answer is almost certainly no, but that may change as people become more comfortable with posthuman technologies and the opportunities they afford for improved health and function.
“What’s crucial about these technologies is they don’t just repair us, they make us better than well,” said Andy Miah, director of the Creative Futures Institute and professor of ethics and emerging technologies at the University of the West of Scotland. “The human enhancement market will reveal the truth about our biological conditions — we are all disabled. This is why human enhancements are likely to become more popular.”
A good example of the way that these technologies are already changing our perception of human identity and notions of disability comes from the world of sport. When Oscar Pistorius donned a pair of carbon-fiber blades to compete alongside able-bodied athletes he offered us a glimpse of a “superhuman” future where Paralympians aided by bionics or performance-enhancing drugs might set hitherto unimaginable sporting records.
POSTHUMAN FUTURE
At the moment, such enhancements are considered unfair, but in a posthuman future in which everyone has access to these technologies, such objections may become moot.
As Bostrom puts it: “If every athlete takes a lot of dangerous performance-enhancing drugs, there will still only be one gold medalist.”
Future prosthetic limbs will be immersed within our flesh, rather than being outside it or replacing it. Athletes will also be able to use 3D printing to create new limbs perfectly tailored to their bodies, or grow replacement body parts when their old ones wear out.
Nor are bionics the only technology transforming norms of health and human performance. For example, in search of enhanced cognitive performance, many people are experimenting with modafinil, a treatment for narcolepsy, while others routinely take selective serotonin reuptake inhibitors (SSRIs) like Paxil and Zoloft to regulate their moods and sense of well-being. These drugs are but the forerunners of a new generation of neuroenhancers and brain stimulation devices that promise shortcuts to even greater intellectual heights.
In Switzerland, which leads the way in many of these technologies and therapies, concerns about the health and ethical impacts are leading to calls for greater regulation. This month, the Swiss Public Health Service reported that adolescent use of methylphenidate, the generic name for Ritalin, had increased by 40 percent between 2005 and 2008, mirroring trends in the US where off-label use is rife among high-school and college students. There is similar concern about the wide uptake of anti-anxiety drugs as pharmaceutical companies seek to redefine social pathologies as treatable psychiatric conditions and aggressively market the therapies to consumers.
The problem is that as technology blurs the distinction between illness and optimal health, it becomes increasingly difficult to distinguish normal from abnormal.
“It’s not only question of human enhancement,” said Anne Eckhardt, the author of a recent report on the opportunities and risks of the human enhancement market for the Swiss Centre for Technology Assessment. “It’s also about medicalization and changing definitions of disease and disability.”
For the moment, this posthuman future still lies some way off. We do not need a brain implant to use Google — Google’s glasses, iPads and mobile phones are, at the moment, more than sufficient for most people’s needs.
“In the long run, technology will surpass our biological nature, but we should not underestimate the technical challenges in getting to that stage,” Bostrom said.
It is an assessment with which Meyer concurs. Since being fitted with his i-limb, Meyer says that actions that used to be unimaginable — such as wheeling a suitcase through duty-free while talking on his mobile phone — he now performs with confidence and ease. However, although the i-limb has enabled him to transcend his feelings of inadequacy and shame, he is a long way from considering himself transhuman, let alone superhuman.
The only point in the Channel 4 documentary at which Meyer appeared to balk at the brave new transhuman future was when he came face to face with “Bionic Bertolt” — the robot bearing his hand and a prosthetic version of his face. He was clearly appalled by the transformation.
“It really freaked me out,” he said.
Meyer’s visceral reaction drove home the extent to which these posthuman technologies provoke visions of dystopian futures, or what Miah pithily calls “the yuck factor.”
Could Asia be on the verge of a new wave of nuclear proliferation? A look back at the early history of the North Atlantic Treaty Organization (NATO), which recently celebrated its 75th anniversary, illuminates some reasons for concern in the Indo-Pacific today. US Secretary of Defense Lloyd Austin recently described NATO as “the most powerful and successful alliance in history,” but the organization’s early years were not without challenges. At its inception, the signing of the North Atlantic Treaty marked a sea change in American strategic thinking. The United States had been intent on withdrawing from Europe in the years following
My wife and I spent the week in the interior of Taiwan where Shuyuan spent her childhood. In that town there is a street that functions as an open farmer’s market. Walk along that street, as Shuyuan did yesterday, and it is next to impossible to come home empty-handed. Some mangoes that looked vaguely like others we had seen around here ended up on our table. Shuyuan told how she had bought them from a little old farmer woman from the countryside who said the mangoes were from a very old tree she had on her property. The big surprise
The issue of China’s overcapacity has drawn greater global attention recently, with US Secretary of the Treasury Janet Yellen urging Beijing to address its excess production in key industries during her visit to China last week. Meanwhile in Brussels, European Commission President Ursula von der Leyen last week said that Europe must have a tough talk with China on its perceived overcapacity and unfair trade practices. The remarks by Yellen and Von der Leyen come as China’s economy is undergoing a painful transition. Beijing is trying to steer the world’s second-largest economy out of a COVID-19 slump, the property crisis and
The past few months have seen tremendous strides in India’s journey to develop a vibrant semiconductor and electronics ecosystem. The nation’s established prowess in information technology (IT) has earned it much-needed revenue and prestige across the globe. Now, through the convergence of engineering talent, supportive government policies, an expanding market and technologically adaptive entrepreneurship, India is striving to become part of global electronics and semiconductor supply chains. Indian Prime Minister Narendra Modi’s Vision of “Make in India” and “Design in India” has been the guiding force behind the government’s incentive schemes that span skilling, design, fabrication, assembly, testing and packaging, and
