In
November 2011 the Japanese announced that their supercomputer “K
Computer,” – the world’s fastest – achieved 10 quadrillion calculations per
second. Don’t laugh. In nerdy tech-geek speak, 10 quadrillion calculations is
shorthand for a petaflop or
floating-point operations per second (I had to look that up). Breaking the
10-petaflop barrier was a big deal, but already US competitors are working hard
to build a supercomputer with twice that speed. Such a computing behemoth could
be going live later this year.
That
may be all well and good. But if an operator were to ask the K Computer what
its emotions concerning love are or for it to express gratitude toward its
creator for being built, I can guarantee you that 10 petaflops or 100 wouldn’t
make much difference. K Computer simply wouldn’t compute.
Why?
Because
even with the best and brightest human
minds working on the problem, artificial intelligence still has a long way to
go. Try as they might, something is lost in translation – reaction time is off,
responses to questions feel forced, and even the worst public speaker on the
planet is liable to excite a crowd better than the tinny voice of a computer,
say, like Watson, the metallic brainiac that beat its human competitors on Jeopardy
last February.
And
that’s exactly the same technological limitations I fear when I read about the
growing virtual campus movement as more and more universities consider adding
virtual classrooms and e-learning opportunities for their students. David
Brooks, in a recent article in The New York Times, rightly points out that
online learning is particularly good at adjusting the learning pace to
individual students as well as the usefulness of assisting remedial students. But
the doubts Brooks raises over online learning’s abilities seem too large to
surmount. He writes:
“Will online learning diminish the
face-to-face community that is the heart of the college experience? Will it
elevate functional courses in business and marginalize subjects that are harder
to digest in an online format, like philosophy? Will fast online browsing replace
deep reading?”
My
short answer to all three questions is an unfortunate, yes – for now. Take
videoconferencing technologies like Skype and Facetime. As a Miami-based public
relations firm, I’ve joined the 31 million Skype
users to communicate with clients as well as staff. While it’s clearly an
improvement over standard phones and conveys more information, (though
pixilated/frozen images can be even more annoying than a dropped call) if I had
the option I’d still prefer to speak to these people in person – to make eye
contact and gauge body language. With Skype and Facetime, users look at
cameras. And it feels that way.
And
it’s that lack of human connection which spills over into Brooks’ second
question. Imagine the quintessential freshman college philosophy course without that genuine real-world
student-teacher give and take? The truth is I wouldn’t want to. As for Brooks’
third concern, “fast online browsing,” is already becoming an epidemic thanks
in part to rapid smartphone adoption and 150-character Twitter feeds. In other
words, small screen sizes and information overload are already threatening
“deep reading” and its requisite offshoot, deep analysis.
Virtual vs. Real
Of
course, technology is always improving and the goal of virtual and simulation
software is to ultimately drop the “virtual” in their names so that what they
produce is indistinguishable from the real world experience. As we approach the
November 2012 presidential election you can be absolutely sure that CNN will
unveil some new virtual teleconferencing equipment. Back in 2008 those efforts
produced a sort-of hologram
that gave viewers the impression that correspondents were in the studio with
Wolf Blitzer. While impressive, the image was more about TV special effects and
less about true holography – 3-dimensional reporters never occupied the CNN
broadcast space. The conclusion: the “hologram” was cool but it proved more of
a distraction (and a way to boost ratings) than it was a way to effectively
deliver information.
As
colleges and universities sign on to offer online and virtual lessons, they
should take this lesson to heart: stay
grounded and keep some human element
to your programs. Introduce students to all the magic videoconferencing,
the mobile web and social media have to offer in an educational capacity, but
let those technologies be explored in the real-world by a flesh and blood
professor, augmenting their lectures, not supplanting them.
That
is, at least until the K Computer – or its 1,000-petaflop relative – learns how
to build the L, M, N, O and P computers without any help from us.
