WELCOME, "MACHINA HUMANA" -- the human machine -- the technologically enhanced suprahuman that might be the future of humankind.
Machina humana will be the primate
species that will at last give substance to the epithet "God-like." Its
ascent will ensure the inevitable decline of Homo sapiens (today's humans) that
have been the species supreme on this Earth for the past 300,000 years.
Centuries to come will see our planet become
an arena pitting two humanoid species against each other for lordship over a Future
Earth one fondly hopes will consist of Geniocracies governed by the
intelligent.
The suprahuman is, of course, the stuff
of countless science fiction fantasies. It will come to pass because Homo
sapiens can't leave well enough alone. Imagine a species arranging its own
demise to advance the cause of science. Only humans can be so stupid. Or,
perhaps, is it because we're too smart for our own good?
This speculative future being I call by
the Latin phrase, Machina humana, will be the offspring of diverse human
technologies seeking to accelerate human evolution without recourse to the
glacially slow and cumbersome process of natural selection.
Technology is, even now, giving birth to
this "thing" in paroxysms of invention. It would be presumptuous to
declare Machina humana the ne plus ultra in “directed evolution,” not when the
rulers of the Earth in tens of millennia hence will look nothing like we
humans.
Machina humana might even be called
"transhuman" and "posthuman." Fans of the mutants in the
Marvel Universe could even say they’re the fantastical "Homo
Superior." Machina humana, as I see it, is beyond the transhuman and
posthuman.
Transhumans/Posthumans
The transhuman is a biotechnologically
enhanced human that sits between humans and posthumans on the evolutionary
scale. It is a being "that resembles a human in most respects but who has
powers and abilities beyond those of standard humans," according to one
definition.
Another posits a transhuman as "a
nanobiotechnological enhancement of humans through applied reason, especially
by using technology to eliminate aging and greatly improve human intellectual,
physical and psychological capacities."
The transhumans’ march towards domination
is predicted by 2030 when true biotechnological fusion between humans and Artificial
Intelligence (AI) is foreseen as coming to pass.
As explained by some of its champions,
transhumans will eventually ascend into the posthuman, a being "whose
basic capacities so radically exceed those of present humans as to be no longer
unambiguously human by our current standards."
The posthuman will become "the
hoped-for transcendence of materiality" bruited about by speculative
philosophers and futurists. This being will exist in a state beyond human; it
will be an amalgam of the organic human, digital, medical and mechanical
technologies and nature.
Evolution to posthuman |
Science will force transhumans to evolve into posthumans using tools such as genetic engineering, bioengineering and a plethora of medical, electronic and mechanical technologies. But it will be in its intelligence that posthumans will shine. One vision sees them as being completely synthetic AI, which is to say a symbiosis of human and AI.
Some might even refer to posthumans by
the archaic term, "cyborg" (cybernetic organism), coined in 1960 to
describe a technologically augmented human with a body both organic and biomechatronic.
Think back to "The Six Million Dollar Man" TV series of 1970 whose
hero (Col. Steve Austin played by American actor Lee Majors) is conferred
superman powers by a bionic left eye, bionic legs and a bionic right arm.
Whatever the appellation, Machina humana
will combine the great qualities attributed to the transhuman and the posthuman.
Machina humana will be superhuman without the impossible
"superpowers" depicted in comic books. Their intelligence, deductive
reasoning and other mental capabilities, as well as their creativity, will
exceed ours.
There will be nothing outwardly visible
that distinguishes a Machina from a human. It will still be human in appearance
and reproduce like one.

What strikes me the most about Machina
humana, however, isn’t its superior intellect or physical powers, but its
superhuman health. These creatures will live to be more than 100 years old and
might even live for over a thousand years.
Only a bioenhanced being, or a mutant,
can attain such obscene longevity. Surviving for centuries means these beings
will have to be incredibly hale and healthy. Only the power provided by medicine,
science, technology and mathematics can attain this result.
Genetic manipulation, bio-hacking,
cognitive enhancement and other biointerventions such as stem cell therapy will
enable Machina humana to remain healthy and physically active beyond today’s
norms. Machina humana might even eliminate physical disabilities and do away
with much of the physical and psychological suffering that bedevils today’s
humans.
Superior longevity and health, however,
will physically alter Machina humana in profound ways. This enforced evolution
will be one reason why people millennia hence will no longer look human.
Their bodies will have to adapt to
survive the assault of new technologies, as well as the Earth's new climate and
ecology due to a much warmer and austere world. It might also include bionic
feet, arms and internal organs that give them the strength to cope with
environments on Earth and on other planets.
We must remember human society has always
been on the march towards Machina humana. Eyeglasses, hearing aids, pacemakers
and prosthetic limbs, to name a few of the simple devices that allow us to
function despite disabilities, can be seen as steps on the road towards Machina
humana. On the other hand, AI and biointerventions are providing the quantum
leap hastening the march towards this being.
The road to the posthuman |
Among those at the forefront of the march
towards transhumans, posthumans and Machina humana are California-based tech
firms such as Neuralink Corporation and the United States Armed Forces, which
are doing so for widely different reasons. American techies and the military
are focusing on perfecting technologies such as the brain-computer interface
(BCI) and one of its iterations called the Stentrode (stent-electrode recording
array) motor neuroprosthesis.
A BCI is a direct communication pathway
between an enhanced or wired brain and an external device such as a computer, a
robotic arm, robotic leg or a weapon. It's also called a mind-machine interface
(MMI) and a brain-machine interface (BMI).
In its civilian guise, BCIs are used for augmenting
or repairing the brain’s human cognitive or sensory-motor functions, among
other things. Neuralink's BCI technology involves ultra-thin probes inserted
into the brain by a neurosurgical robot, as well as a high-density electronic
system to process information from the brain’s neurons.
The probes are made mostly of polyimide
(a high-performance, biocompatible thermoplastic polymer) with a gold or
platinum conductor. Each probe consists of an array of wires whose electrodes can
locate electrical signals in the brain. The electronic system will amplify and
acquire brain signals while using Bluetooth to communicate with external
devices.
Neuralink said its BCI technology will
one day help people control computers with their brain activity alone. BCI will
also boost cognitive capabilities like speech and sight, and should be capable
of restoring the ability to speak.
Neuralink "is aiming to bring
something to market that helps with certain severe brain injuries (stroke,
cancer lesion, congenital) in about four years,” said company co-founder and
CEO Elon Musk in 2017.
In July 2019, Musk said the company
wanted to have its first human patient equipped with the technology before the
end of 2020. That didn’t happen and the world is still waiting for it to occur.
Instead, Neuralink in April 2021 demonstrated a monkey with an implanted
Neuralink BCI playing the 1972 classic ping-pong video game, "Pong.” Musk
also believes future humans might communicate with one another using technological
telepathy.
The great goal of Neuralink’s BCI
technology, however, is human enhancement -- or the creation of the transhuman.
Musk later confirmed this long-term goal, saying Neuralink wants to achieve
"symbiosis with artificial intelligence,” but as a defense against what
Musk believes will be a future AI apocalypse. Musk hopes to "help secure
humanity's future as a civilization relative to AI" with Neuralink’s BCIs.
Neuralink Brain Computer Interface or BCI |
While Neuralink is falling behind on
keeping its promises, the U.S. military appears to be forging irresistibly
forward with the development of Stentrodes for its future fighting men. Conceived
in 2010 by Australian neurologist Dr. Thomas Oxley MD, a Stentrode is a
miniscule electrode array made of platinum mounted on a nitinol (nickel
titanium) endovascular stent. The Oxley Stentrode measures some five centimeters
long; its diameter comes to only four millimeters.
The Stentrode is capable of two-way
communication, which means it can sense thoughts and stimulate movement. Basically
a feedback loop within the brain, the Stentrode is the first motor
neuroprosthesis (or a BCI) implanted via a patient's blood vessels.
Once in position, a Stentrode expands to
press electrodes against the blood vessel wall close to the brain. Here, it digitally
records neural information and delivers electric currents directly to targeted brain
areas.
The system digitizes signals generated by
the cerebellum (the part of the brain that controls movement). It then
translates these signals into commands a computer equipped with special
software can read and execute.
A most successful Stentrode test on
humans was conducted in 2020. The two test participants suffered from ALS
(amyotrophic lateral sclerosis), a brain disease that causes the deterioration
and death of the motor neurons controlling voluntary muscle movements such as
walking and talking. The late great theoretical physicist Dr. Stephen Hawking
was an ALS victim.
With Oxley’s Stentrodes, both
participants were able to use direct thought to wirelessly control a computer operating
system that allowed them to text, email, search the internet and shop online. This
historic feat was also the first time a BCI was implanted via blood vessels, thus
eliminating the need for dangerous and difficult open brain surgery.
The Oxley stentrode |
Oxley's research team based in Australia is
receiving funding for its Stentrode research from the U.S. Defense Advanced
Research Projects Agency (DARPA) as part of the Reliable Neural-Interface
Technology (RE-NET) program. Oxley founded Synchron, Inc., a start-up building
BCIs and Stentrodes, and is now co-head of the Vascular Bionics Laboratory at
the University of Melbourne.
The American military still sees the Stentrode
as a critical step in the process to transform future U.S. soldiers into
"cyborg warriors." These fighting men are directly connected to
battlefield computers and computer-controlled weapons, and are able to
"talk" to them telepathically. The military Stentrode is also expected
to enable U.S. soldiers to move and react faster on the battlefield.
For the U.S. Air Force, the long-term aim
is to create a “novel hybrid brain-machine interface” that improves its
airmen’s ability to learn and make more rapid, effective decisions, especially
in combat. It’s continuing to develop an “augmented learning platform,” or a Stentrode,
to make the brain more receptive to imbibing information.
The Stentrode will transform American
fighter pilots into true cyborgs. Oxley in 2016 said DARPA wants U.S. Air Force
fighter pilots to control their jets directly by plugging their brains into the
aircraft's computer system.
"The military appear interested in
the potential for jet fighters to control their planes with direct thought
control, rather than using their arms,” Oxley revealed. “The reaction time
you'd shave off would be milliseconds."
Blitz-fast reaction could spell the
difference between life and death for American fighter pilots in supersonic
aerial battles. A Stentrode might also reduce stress among American fighter
pilots since flying computer-controlled warplanes such as the Lockheed Martin F-22
Raptor air superiority fighter and the stealthy Lockheed Martin F-35 Lightning
II is physically taxing.
Piloting these complex flying computers requires
a pilot to evaluate and monitor several actions occurring simultaneously. Stentrodes
are also expected to reduce pilot error.
The U.S. Navy is getting into the act.
Its Neural Engineering System Design program being implemented by DARPA is developing
an “implantable neural interface” (a Stentrode) that should give
"unprecedented signal resolution and data-transfer bandwidth" to
fighter pilots on its fleet of nuclear-powered aircraft carriers.
It’s clear a cyborg soldier’s enhanced
abilities derive from technologies such as the Stentrode and other types of
BCI. The cyborg warrior as envisioned by the U.S. military, as well as Neuralink’s
BCI, will mean the rise of the transhuman, the posthuman and Machina humana is
all but certain.
Only a way station
Machina humana, however, will only be a
way station leading to the "Ultima." Thousands of years from now
might see the rise of the truly "God-like being" I call the Ultima.
The dawn of the Ultima will be historic.
Ultima will no longer look like human beings; they might even be grotesquely
loathsome by today’s human standards of physical beauty.
It is to be hoped, however, that Ultima
will be far, far better versions of us. Yes, Ultima will be vastly intelligent
and physically stronger. But it might also be less bigoted; less murderous;
less warlike -- and more altruistic and more sapient.
Ultima will be a new human species
completely alien to Homo sapiens. They will be the aliens amongst us, but will
still be "us" in a paradoxical way.
Our inhuman future looks bright.
