Hitler would have loved The Singularity: Mind-blowing benefits of merging human brains and computers

Of all the tall tales in the science-fiction TV series Star Trek, what impressed me most when I was a little boy was the Vulcan mind meld.
Laying his hands on the head of a human (or, in one of the films, a humpback whale), Mr Spock could, for a moment, dissolve the distance between two living things.
Each experienced everything the other felt, thought, knew and saw.
Now it seems scientists are about to make the Vulcan mind meld a reality – and go far beyond it.
Ten years ago, the US National Science Foundation predicted ‘network-enhanced telepathy’ – sending thoughts over the internet – would be practical by the 2020s.
Man and machine: Computers could soon be hardwired into the human brain and unlock amazing power.
And thanks to neuroscientists at the University of California, we seem to be on schedule.
Last September, they asked volunteers to watch Hollywood film trailers and then reconstructed the clips by scanning their subjects’ brain activity.
‘We’re opening a window into the movies in our minds,’ Professor Jack Gallant announced.
Last week, the scientists boldly went further still. They charted the electrical activity in the brains of volunteers who were listening to human speech and then they fed the results into computers which translated the signals back into language.
The technique remains crude, and has so far made out only five distinct words, but humanity has crossed a threshold.
We can now read people’s minds. On Star Trek, the Vulcan mind meld had medical benefits, curing a nasty imaginary infection called Pa’nar syndrome.
Science fact: Harnessing the power of the mind was a favourite of science fiction, including Star Trek’s Vulcan mind meld
But the new breakthroughs promise to deliver much greater – and real – benefits.
No longer need strokes and neurodegenerative diseases rob people of speech because we can turn their brainwaves directly into words.
But this is only the beginning. Neuroscientists are going to make the mind meld look like child’s play. Mankind is merging with its machines.
The process began centuries ago with simple devices such as eyeglasses and ear trumpets that could dramatically improve human lives.
Then came better machines, such as hearing aids; and then machines that could save lives, including pacemakers and dialysis machines.
By the second decade of the 21st Century, we have become used to organs grown in laboratories, genetic surgery and designer babies.
By 2020 we may be able to put even cleverer nanocomputers into our brains to speed up synaptic links, give ourselves perfect memory and perhaps cure dementia.
But inserting technology into human brains is not the only thing going on. Some scientists also want to insert human brains into technology.
Since the Sixties, computer chips have been doubling their speed and halving their cost every 18 months or so.
If the trend continues, the inventor and predictor Ray Kurzweil has pointed out that by 2029 we will have computers powerful enough to run programs reproducing the 10,000 trillion electrical signals that flash around your skull every second.
They will also have enough memory to store the ten trillion recollections that make you who you are.
Dangerous technology: The huge potential unlocked by the technology raises frightening prospects if it were to be used by evil dictators like Adolf Hitler
And they will also be powerful enough to scan, neuron by neuron, every contour and wrinkle of your brain.
What this means is that if the trends of the past 50 years continue, in 17 years’ time we will be able to upload an electronic replica of your mind on to a machine.
There will be two of you – one a flesh-and-blood animal, the other inside a computer’s circuits.
And if the trends hold fast beyond that, Kurzweil adds, by 2045 we will have a computer that is powerful enough to host every one of the eight billion minds on Earth.
Carbon and silicon-based intelligence will merge to form a single global consciousness.
Kurzweil calls this ‘The Singularity’, a moment when ‘the pace of technological change will be so rapid, its impact so deep . . . that technology appears to be expanding at infinite speed’.
At that point, we will have left the Vulcan mind meld far behind. But even this may not be the end of the story.
Much of the research behind last week’s breakthrough in brain science was funded not by universities but by DARPA, the US Defence Advanced Research Projects Agency.
It was DARPA that brought us the internet (then called the Arpanet) in the Seventies, and DARPA’s Brain Interface Project was a pioneer in molecular computing.
More recently, DARPA’s Silent Talk programme has been exploring mind-reading technology with devices that can pick up the electrical signals inside soldiers’ brains and send them over the internet.
With these implants, entire armies will be able to talk without radios. Orders will leap instantly into soldiers’ heads and commanders’ wishes will become the wishes of their men. Hitler would have loved it.
Cyborg-soldier: The defence industry could soon try implanting computer technology into the brain of soldiers
Some of the clearest thinking about the new technologies has been done in the world’s departments of defence, and the conclusions the soldiers draw are alarming.
For example, US Army Colonel Thomas Adams thinks that military technology is already moving beyond what he calls ‘human space’, as robotic weapons become ‘too fast, too small, too numerous, and . . . create an environment too complex for humans to direct’.
Technology, Col Adams suspects, is ‘rapidly taking us to a place where we may not want to go, but probably are unable to avoid’.
As goes war, so, perhaps, goes everything else. The merging of mankind and its machines that Kurzweil predicts for the mid-21st Century may, in fact, turn out just to be a lay-by on the way to a very different destination.
Later in the century, what we condescendingly call ‘artificial’ intelligence might replace us humans just as thoroughly as we humans once replaced all our evolutionary ancestors.
All this will come to pass . . . unless, of course, it doesn’t. Maybe the trends Kurzweil and Col Adams identify will slow down, or even stall altogether.
And maybe the critics who mockingly call the Singularity ‘the Rapture for Nerds’ will be proved right.
But on the other hand, maybe the Nobel Prize-winning chemist Richard Smalley is closer to the truth when he points out: ‘When a scientist says something is possible, they’re probably underestimating how long it will take.
But if they say it’s impossible, they’re probably wrong.’
The University of California’s neuroscientists have taken us one more step towards a final frontier far beyond anything dreamed of in Star Trek.
“The advancement of techniques propel us toward the third step in the Blue Beam Project that goes along with the telepathic and electronically augmented two-way communication (nano brain implant) where ELF, VLF and LF waves will reach each person from within his or her own mind, convincing each of them that their own reality is speaking to them from the very depths of their own soul. Such rays from satellites are fed from the memories of computers that have stored massive data about humans on earth, and their languages. The rays will then interlace with their natural thinking to form what we call diffuse artificial thought.”
So how could that be possible you ask? Easy. Enter Project Joshua Blue, currently under development by our favourite business machines company, IBM. Joshua Blue is a program with the stated goal of “Evolving an Emotional Mind in a Simulated Environment”, “to enhance artificial intelligence by evolving such capacities as common sense reasoning, natural language understanding, and emotional intelligence, acquired in the same manner as humans acquire them, through learning situated in a rich environment.”
