Silicon Valley Wants Inside Your Head—Literally

A recent article in the engineering professional’s
magazine IEEE Spectrum reveals that several
powerful Silicon Valley entrepreneurs are sponsoring initiatives to breach the
barrier separating our brains from the rest of the world.  They all fall into the category of
“brain-computer interfaces” or BCIs. 

For example, Facebook wants to develop a noninvasive
(meaning you don’t need surgery to wear it) system that would let you type five
times faster on your smart phone than you do now.  A former Facebook executive named Mary Lou Jepsen is trying
to develop an MRI-type device that will “interpret the patterns of neural
activity associated with thoughts”—mind-reading, in other words.  Elon Musk, true to form, has thrown
caution to the winds with his program to implant a sensor in your brain,
bypassing the old-fashioned eyes, ears, and fingers and mainlining the Internet
straight to your hippocampus, or wherever the thing will be attached. 

There are two things I’d like to say about these
projects.  One is technical, and
the other is moral.

The technical aspects of BCI projects are daunting,
to say the least.  While some
research has been done already into ways of communicating with the brains of
people with “locked-in” syndrome (e. g. sufferers from Lou Gehrig’s
disease who can no longer move any voluntary muscles), progress has been slow
and the systems have been customized to each individual.  The brain is the final frontier of
biology, in that it is the most complex organ known and probably the one we
know the least about in comparison to what there is to know—which, in a sense,
is all human knowledge, since all human knowledge is, materially speaking,
contained in brains.  The
self-reflexive nature of brain research makes me wonder if there isn’t
something analogous to Gödel’s incompleteness theorems at work in the brain’s
attempt to understand how the brain works. 

Mathematician Kurt Gödel showed in 1931 that every
mathematical system of a certain complexity is bound to have statements in it
that cannot be either proved or disproved without going outside the
system.  The brain analogy of this
is that the brain may not be able to understand exhaustively everything about

Whether or not that is the case is a purely
speculative question at this point—just the kind of issue that the Silicon
Valley types are not interested in. 
They want to do something with
the brain, not understand it, and their research is way toward the development
end of R&D, with explicit timelines and the whole apparatus of high-tech
development programs favored by those with essentially infinite amounts of

What a contrast it is to the way some wealthy
corporations used to behave. 
Physicist Mark P. Mills points out in a recent article in the journal New Atlantis that U. S. corporations
spend only about 7% of their total R&D money on basic research, which the
government’s Office of Management and Budget defines as “study directed
toward fuller knowledge or understanding of the fundamental aspects of
phenomena and of observable facts without specific applications toward
processes or products in mind.” 
Mills makes the telling point that while the basic-research labs of the
old pre-breakup Bell System and IBM can count thirteen Nobel Prizes to their
credit, the free-spirited pursuit of knowledge wherever it leads is no longer
in favor in the U. S. corporate world. 
Though the lag between a discovery and the awarding of a Nobel Prize can
often be decades, Mills looks in vain for any comparable scientific
achievements from the tightly-application-focused “moon-shot”
projects currently favored by Silicon Valley.

The technical point here is that those pursuing BCIs
may have bitten off more than they can chew, and the nature of the problem
might require a longer-term, less focused perspective.  Even if the goal of brain-computer
interfaces is worthy of pursuit, we may be in for a long marathon instead of a

Now for the moral issue.  Is it right to read another person’s mind?  Especially if they are not fully aware
of what is involved in the process? 
Ah, the corporations say, we would never do such a thing without your
consent.  Yes, I reply, the same
kind of consent I give whenever I load a new piece of software on my computer
and lie that I have read and understood eight pages of legal gobbledegook when
I click the button that will let me load the software. 

We have already been trained to allow snooping at a
scale that twenty years ago would have been regarded as outrageous.  Everyone who gets online has probably had
the experience of doing a web search for a consumer item in one place, only to
find ads for it popping up later during a completely unrelated activity.  A combination of cookies and
data-sharing among Internet companies on a grand scale means that privacy, at
least when it comes to things you search for online, is mostly a thing of the

Should we let the greedy hands of the Internet reach
into the last remaining sanctuary of privacy, the human mind itself?  I am reminded in this connection of a
passage in one of C. S. Lewis’s Chronicles
of Narnia
series, The Voyage of the
Dawn Treader
.  In it one of the
English children transported to Narnia is named Lucy, and at one point she is
alone in a magician’s house, perusing a great book of magic.  She comes upon a spell “which
would let you know what your friends thought about you.”  She says the magic words, and a kind of
television process shows her two friends of hers in a train.  She hears them talking about her, and
not in a nice way, either. 

A bit later, Aslan the Lion appears, and says to her,
“Child. . . I think you have been eavesdropping.”  When she replies that she didn’t think
it counted as eavesdropping if it was magic, he replies “Spying on people
by magic is the same as spying on them in any other way.”  I don’t know how popular the Chronicles are in Silicon Valley, but
it’s just possible that a moral lesson a child could understand needs to be
taught to some of our most powerful technical leaders.
