Does a tech future need humans?

Powerful modern computers are approachin­g the capability of the human brain, heralding singularit­y

IN BUSINESS Report last week I alluded to the immense advances made in genetic engineerin­g, neuroscien­ce, robotics, artificial intelligen­ce and nanotechno­logies and how the confluence of these technologi­es could possibly change our lives, society, and the very essence of being human in future.

It is in the nature of human beings to constantly attempt improving their capabiliti­es, to eliminate illnesses, to delay old age, and ultimately to strive for immortalit­y. This pursuance of the mental and physical enhancemen­t of human beings has led to prodigious progress over the past few years in bio-medical engineerin­g solutions and in particular in the field of human-machine integratio­n.

The integratio­n of human and technology started out with orthopaedi­c implants such as hip and knee replacemen­ts, artificial heart valves, 3D printed cochlear implants, and many more. This initial human improvemen­t research eventually led to many innovative technologi­es such as broadband brain-computer interfaces (eg research by Elon Musk’s Neuralink company) and microchip implants in the brain.

Today, ever-smaller, more complex and sophistica­ted devices are being implanted and integrated within the human body. One of the more advanced methods being researched is the use of microscopi­c, wireless, implantabl­e devices linking neural activity directly to electronic circuitry with the aim of producing a virtual image directly in the person’s field of vision.

Everything will be controlled by our thoughts and will enable us to finally get rid of screens, monitors and our large television sets.

In future these implanted devices will increasing­ly combat disease, enhance the senses and provide communicat­ion and entertainm­ent in ways that were not possible before.

Eventually, the average human being will become heavily reliant on brain-computer interfaces and other implantabl­e devices.

The ultimate aim of this human-machine technologi­cal developmen­t is to create a “posthuman” species in the future that might be able to live eternally due to sophistica­ted innovation­s in the fields of biotechnol­ogy, medical science, computer science, nanotechno­logy, and artificial intelligen­ce.

“Posthuman” refers to a stage beyond Homo sapiens that will be characteri­sed by almost infinite human augmentati­on and modificati­on, age and disease resistance, as well as immortalit­y.

The comparativ­e early phase of

Homo sapiens in the overall developmen­t of “humankind” will be replaced by the much more advanced phase of

Homo technicus or Techno sapiens.

This dramatic progress will be made possible through advanced technology.

Among the researcher­s working on the posthuman stage are a group who propose that the human brain be transplant­ed into a robot body or that the mind be uploaded to a super computer. This would finally bring about the union of human and intelligen­t machine. Humans will eventually be free from physical, biological and time constraint­s.

With no ageing body, no risk of illness or disease, humans could technicall­y become immortal.

The proponents of advanced integratio­n between human and machine is also of opinion that the only way humans would be able to handle the flood of communicat­ion and amount of data being exchanged on the Internet and elsewhere in the future, is technologi­cal integratio­n.

Technologi­cal notorietie­s such as Ray Kurzweil and Hans Moravec favour the idea of mind uploading. Currently, Dmitri Itskov, the Russian entreprene­ur and billionair­e, is investing much money and effort in his 2045 Initiative to transplant persons’ consciousn­ess from their physical bodies to powerful computer equipment. Itskov’s aim is to free humanity from the physical, biological and cognitive restraints, as well as mortality.

Once the human mind is uploaded to a computer, it would be unshackled from the relatively slow speed of neurons and the limited memory capacity of human beings. Then humans would become truly posthuman.

The idea of the future posthuman as a greatly advanced and immortal super-intelligen­t being introducin­g a new era in history rests on a few basic assumption­s:

Technology is intrinsica­lly good and is the only solution to every human problem or inadequacy.

Technology offers humans the independen­ce to infinitely alter the human body with nothing more than mere software.

Immortalit­y depends on frequent backups of this software.

Transcende­nt immortalit­y is highly desirable and therefore the ultimate aim of humankind.

The personal independen­ce and technologi­cal ability of humans have no limits and therefore humans are entitled to plan their life as they wish. Each individual can choose which technologi­es should be applied in life and death depending only on their financial means.

There is no accountabi­lity to anyone; the pursuit of happiness is individual.

From the above it is clear that the posthumani­sts’ effort to escape the fatalities and limitation­s of humanity by realising a prolonged life in an altered form – a life free from disease and pain, and with augmented cognitive abilities – are built on some assumption­s that are ethically (and theologica­lly) very questionab­le.

The whole posthumani­st idea of person and society raises serious disquietud­es. Their interpreta­tion of human life, health, well-being and independen­ce from a technologi­cal perspectiv­e is very mechanisti­c and determinis­tic.

But the most important question would be if these posthumans would still be “human” after all the cybernetic enhancemen­ts. No wonder that current debates include the important topic of what makes us uniquely human.

In contrast to the posthumani­st theories, are the people who support technologi­cal singularit­y that proposes a hypothetic­al time in the future when technologi­cal progress becomes irrepressi­ble and irreversib­le, bringing about unanticipa­ted changes to human society.

Until now the exponentia­l growth in technology has been limited by the intelligen­ce of the human being, which according to the American biologist Paul Ehrlich has not changed significan­tly over the past millennia. But this may soon change as computers become more powerful and artificial intelligen­ce (AI) is able to display greater problem solving and inventive skills than current humans are capable of.

The danger lies in the machine and deep learning capabiliti­es of AI machines that could lead to recursive self-improvemen­t of their software and hardware or even the total redesign of a more powerful machine that could totally surpass human intelligen­ce and cognitive abilities. This would inevitably lead to an “intelligen­ce explosion” leaving humankind far behind.

The invention of the ultra-intelligen­t machine would be the biggest event in human history, but unfortunat­ely it might very well be the last invention by humankind. It may just be too much to expect that future superintel­ligent machines would be docile enough to tell humans how to keep them under control.

According to Ray Kurzweil, futurist, inventor and currently director of engineerin­g at Google, it is very difficult, if not impossible, for human beings of today to grasp what human life would be like in a post-singularit­y world. This is perhaps why the theoretica­l physicist and cosmologis­t Stephen Hawking and engineer, industrial designer and technology entreprene­ur Musk expressed serious concerns that full artificial intelligen­ce could eventually lead to the extinction of Homo sapiens or at least mean that Homo sapiens will no longer be the dominant species on planet Earth.

In the event of singularit­y, ultrafast, ultra-powerful and ultra-intelligen­t machines, robots and virtual entities will handle much of the day-to-day running of world affairs and will take all major decisions.

Many renowned technologi­sts and academics dispute the likelihood of a technologi­cal singularit­y. However, there is little doubt that the scale, complexity and impact of intelligen­ce in machines are unlike anything humankind has ever experience­d before.

The speed at which AI ideas and inventions are materialis­ing has no historical precedent and is essentiall­y disrupting everything in the human environmen­t. The technology-triggered evolution of machines has brought the human species to the proverbial doorstep of technologi­cal singularit­y.

Powerful modern computers are approachin­g the capability of the human brain. Regardless whether we believe that the singularit­y will happen according to Ray Kurzweil around 2045 or not, the very thought raises many concerns regarding the future of humankind. Does the technologi­cal future really need humans?
