One morning in a
not-too-distant future, you’re reading a news article suspended in
the air with your nano-wafer contacts while on the way to work in a
driverless flying taxi. Suddenly, your wife calls you. Instead of
picking up the smartphone, you accept the “call” with a flicker
of thought, and her voice fills your mind as she reminds you
that the kids have swimming lessons today.
The late author Iain Banks imagined a similar world where humans can communicate mentally
with each other and with machines in his acclaimed The Culture series. Brain-to-brain interfaces may be the stuff of science
fiction, but scientists and visionary entrepreneurs are working
toward realizing that world today.
A recent
MIT study outlines a device that allows the wearer to interact with a computer
without speaking aloud or typing. The device, called “AlterEgo,”
picks up on neuromuscular signals to reconstruct what you say, then
relays that to a computer.
Arnav Kapur, one of
the paper’s authors, told Popular Science that it’s
not exactly speaking or thinking, but more like telling a computer –
such as Siri or Alexa – what to do by talking silently to yourself
without moving your mouth.
The tech is still in
its prototype stage as the study’s authors say they hope to expand
the vocabulary that the device can interpret, but it shows us that
current technological trends can eventually free humans from the
shackles of speech.
Rajesh Rao came even
closer in 2013. Back then, the University of Washington researcher
successfully controlled his colleague’s hand – with his
brain. In the first demonstration of human brain-to-brain
communication, Rao was able to move researcher Andrea Stocco’s
right index finger simply by imagining the motion while playing a
video game, according to a university press release. Both were on
opposite sides of the campus wearing caps fitted with electrodes to
pick up the brain’s electrical signals, which were then transmitted
over the Internet.
Even Elon Musk, the
eccentric billionaire entrepreneur who has his fingers in rockets and
electric vehicles, jumped into the fray by co-founding Neuralink. He
plans to fully develop brain-machine interfaces with tech inspired by Banks called “neural lace,” which are electrodes implanted
in the brain to augment our minds with the computing power of
machines.
If realized, the technology would yield endless possibilities, such as allowing us to
absorb and process information at tremendous speeds, and helping
those with memory loss by enhancing their cognitive capabilities.
But, as with many of
Musk’s endeavors, his involvement in this enterprise is intended to address
a greater concern. In the age of AI, he said at a 2017 summit in
Dubai, humans must merge with machines to stay competitive. There is a growing worry that a society run by intelligent machines would cause
mass unemployment, while more optimistic scenarios – such as those
depicted by Banks – paint a world where humans enjoy limitless
material abundance and freedom from labor thanks to automation.

Widespread use of
tech-enabled telepathy and superhuman cognition seems far into the
future. Kapur’s “AlterEgo” takes up half your face and Rao’s
brain caps have wires connected to a machine, all of which are rather
obtrusive designs that would get more than a few stares in public.
But wearable technology has a habit of becoming intimate. When such
devices are no longer mere extensions of our capabilities but
challenge our very notions of humanity, will we eagerly adopt them? Most likely – as long as we look good doing so.
