University Alert: The Information Railroad Is Coming
Wm. A. Wulf
University of Virginia
It's New Year's Day, 1895. My name is
Hans. For seven generations my family has made the finest buttons in
the region, using the good local horn.
Today I learned that the railroad is coming to our village. My
friend Olaf says that cheap factory buttons will come on the trains,
but they will never compete with my craftsmanship.
I think he is right, and wrong. They will come, but they will
compete with my buttons. I must make some choices. I can become a
distributor for the new buttons, or I can invest in the machinery to
make buttons and export them. Or, closest to my heart, I can refine
my craft and sell exceptional buttons to the wealthy.
My family's business is dead. I cannot stop the train; I must
change.
Universities are in the information business, and the information
railroad is coming.
With 20-20 hindsight it's easy to accept the demise of a quaint
industry or more accurately, the demise of a quaint method
of manufacture, distribution and sale. The button industry
flourishes, of course. Even the craft of hand made buttons is doing
well, if my local art fair is any indication. However, the nature of
the industry changed dramatically as technology allowed the
manufacture and distribution of vastly less expensive but highly
serviceable buttons.
It's harder to look inward at the university, with its tradition
and obvious social value, and introspect about whether it might
change in dramatic ways. But, although their roots are a millennia
old, the university has changed before. In the early nineteenth
century it embraced the notion of secular, "liberal" education. In
the late nineteenth century it included scholarship as an integral
part of its mission. After World War II it accepted an implied
responsibility for national security, economic prosperity, and public
health in return for federally funded research. Although the effect
of these changes have been assimilated and now seem "natural", at the
time they involved profound reassessment of the mission and structure
of the university as an institution.
Forces are always acting on universities. Some of them, notably
the political ones, have great immediacy and hence get a good deal of
attention . In the current milieu these include the reassessment of
the rationale for federal funding of research, the desire for greater
"productivity" from the Professoriate, and so on. In spite of the
attention accorded these issues, I believe information technology has
a far greater potential to provoke fundamental change in our system
of higher education. Moreover, I am certain these changes are much
closer than most people realize.
Let me be clear. Higher education will flourish, just as does the
button industry. If anything, the need for advanced education is
increasing simultaneously in multiple dimensions. A greater
percentage of the world's population needs to be educated to be
productive in an increasingly technological workplace. The period
during which particular skills are relevant is shortening, and so the
need for "lifelong learning" is increasing. The knowledge and skills
necessary to function at the frontier of knowledge are increasing as
well, and so with it the need for advanced degrees.
Higher education is not in danger. But we would be wise to ask
whether the particularly quaint way that we manufacture, distribute
and deliver that education will survive the arrival of the
information railroad. They may, but I don't think so. I think there
will be major changes changes not only in the execution of
the mission of universities, but in our perception of the mission
itself.
As Clark Kerr pointed out , the relative ranking of universities
changes slowly, but there are times that are more propitious than
others for change, and the next decade is one such. Because of the
speed with which information technology is advancing, decisions are
being made now or more likely, defaulted now that
will have material effect on the real and perceived quality of
institutions of higher education. In my experience almost none of
the current generation of senior university administrators understand
what is happening.
Thus, I feel we must engage in an intellectually honest exercise
of understanding the implications of technology on our institutions
at least as best we can. Stimulating that discussion is my
purpose here. But, before proceeding we need to dispense with two
issues: First, is the button analogy valid? Second, is the technology
for higher education really going to change all that much?
Certainly some specifics of the button parable are inappropriate
universities don't make a product that can be mechanically
mass produced, for example. But while pointing out the differences,
it would be a mistake to dismiss the similarities. Both are highly
labor intensive and depend on the skill of their master craftsmen.
Both have been regional, requiring collocation of the producer and
customer. Both have long traditions. Both contributed to the prestige
of their locale. Both evolved powerful guilds to protect the masters.
And, now the university is also faced with a technological
revolution.
Universities share at least some of the attributes of other
vertically-integrated industries as well. We "manufacture"
information (scholarship) and occasionally "reprocess" it into
knowledge or even wisdom, we warehouse it (libraries), we distribute
it (articles and books), and we retail it (classroom teaching).
Information technology has already changed each of these, and the
future change will be much greater. Like industries that have been
overtaken by technology, we need to understand its individual and
collective impact on our basic functions. It's not a comfortable
thought, but we must at least consider that a change in technology
a change that will facilitate the flow of our essential
commodity, information might provoke a change in the nature
of the enterprise.
As for information technology one of the hardest things
for most people to understand is the effect of its exponential rate
of improvement. For the last four decades the speed and storage
capacity of computers have doubled every 18-24 months; the cost, size
and power consumption have become smaller at about the same rate. The
bandwidth of computer networks has increased a thousand-fold in just
the last decade, and the traffic on the network continues to grow at
300-500% annually. For the foreseeable future, all of these trends
will continue; the basic technology to support them exists now.
The compound effect of this rate of improvement is hard to
appreciate but, speaking of ENIAC, the first fully
electronic digital computer, a 1949 article in Popular Mechanics
said:
" ENIAC contains about 18,000 vacuum tubes and weighs 30 tons, but
in the future computers will contain only about 1,000 tubes and
weigh only 11/2 tons."
Thirty five years later a typical microprocessor is about 100,000
times more powerful, contains the equivalent of ten million tubes and
weighs substantially less than an ounce. Imagine the nanoprocessor of
the a few decades hence.
To my knowledge, there has never been a similarly rapid, sustained
change in technology, especially one with such broad social
application. By comparison, even the industrial revolution seems
modest in scope and leisurely in pace. Lacking a precedent, we need
to work harder to imagine the impact of future computers and
networks. Thinking about the current ones, in fact, can be
misleading; it's all too easy to assume that something won't change
just because today's technology doesn't support that change. Instead,
it's almost better to hypothesize a change and then ask how soon the
technology will support it; the answer will often be surprisingly
soon.
Don't think about today's teleconferencing technology, but one
whose fidelity is photographic and possibly three dimensional. Don't
think about the awkward way we access information on the network, but
one in which the entire world's library is as accessible as my
desktop files. Don't think about the clumsy interface to computers,
but one that literally listens and talks in your jargon, not mine.
Don't think about the storage on today's PC, but one with terabytes
(millions of megabytes). We can't afford it now, of course, but that
is the power of the equipment that will be affordable in a decade or
so. That is the equipment that will shape the future of the
university.
How will we use this equipment to change education and
scholarship? That seems like a simple question, but as both an
academic and a Computer Scientist, I don't know. Certainly knowledge,
its creation, storage and communication, is part of the essence of a
university. The ability to process information, the "raw stuff" of
knowledge, thus sits at the heart of the university mission. A
technology that will alter that ability by orders of magnitude cannot
avoid having a impact on at least how we fulfill our mission
and possibly on the mission itself.
To borrow a phrase from the business world, information technology
is a "core competence" of our industry; the leaders in developing
and exploiting it will be the leaders of the next century. This is
one of Kerr's "propitious times".
Perhaps as a start we might look at several functions of our
vertically integrated information business and note how they have
been and might be changed.
Scholarship: The impact of information technology on science is
both apparent and pervasive. Scientists now routinely talk of
computation as the "third modality" of scientific investigation, on a
par with theory and experimentation.
The easy examples are those that simply automate what was done
manually: the reduction of data, the control of instruments, etc. The
profound applications, however, are those that lead to whole new
areas of research and new methods of investigation and thus
to science that was not, and could not be done before: the final
proof of the four color conjecture, analysis of molecules that have
not been synthesized, measuring the properties of a single neuron by
growing it on a silicon chip, watching a model of galaxies collide,
and letting a scientist "feel" the forces as a drug docks in a
protein. These applications have transformed the nature of scientific
investigation; they led to questions that would not even have been
asked before.
I don't think science, however, will be where we see the most
dramatic impact. I say that despite a recent report from the National
Research Council that I helped coauthor a report that
paints an expansive image of the transformation of scientific
research. Instead, I believe that a more dramatic transformation is
about to shake the foundations of scholarship in the liberal arts.
Humanists more than scientists will lead the way to innovative
applications of the technology in the university.
The comfortable stereotype of humanists as technophobic just
doesn't apply anymore. The availability of both text and images in
electronic form coupled with the processing power of modern computers
allow the humanist to explore hypotheses and visualize relations that
were previously lost in the mass of information sources. The
presentation of humanists' scholarly results in electronic form is
moving even faster. Precisely because of the complexities of the
relationships they need to present, the subtle webs of relation and
inference they need to express, electronic "hypertext" books and
journals are emerging. Indeed, they are emerging faster, with more
vigor, and with more effect on their disciplines than their
counterparts in the sciences.
We all expect scientists and engineers to use computers in their
research, but the notion that information technology could be central
to humanistic scholarship is a bit more startling at least
to me. It was in large measure talking about the application of
computers to historiography and the theory of text that opened my
eyes to the larger issues that I am trying to raise here.
Textbooks: I don't know anyone who prefers to read from a computer
screen, and besides you can't take a computer to the beach
or so say the nostalgic. They are right, and yet so profoundly wrong.
There are two fallacies here. The first is the assumption that
electronic books will contain only text, and hence be the essentially
the same as paper books but presented differently. In reality, it
will not be possible to reproduce an electronic book on paper. They
will not be a simple linear presentation of static information. They
will contain animation and sound. They will let you "see the data"
behind a graph by clicking on it. They will contain multidimensional
links so that you can navigate through the information in ways that
suit your purpose rather than the author's. They won't contain
references to sources, but the source material itself the
critique of a play will "contain" its script and performance. They
will have tools that let you manipulate the equations, trying them on
your own data or modifying them to test scientific hypotheses. They
will let one annotate and augment the documents for use by later
readers, so making it a "living document".
The second fallacy is presuming today's technology. We should not
be talking about reading these electronic books from today's screen.
The advantages of the electronic book will be so strong that
engineers will make the "form factor" of the medium humane. Screens
already exist in the laboratory with a resolution about the same as
the paper you are reading right now as do flexible ones of
somewhat lower resolution. Why would anyone lug around several heavy
books when something the size, clarity and weight of a single one
contains them all? I mean them all all the ones in the
Library of Congress. I will take my computer to the beach!
Libraries: For thousands of years the focus of libraries has been
on the containers of information, books. The information itself was
the domain of the library's users, not the library. Information
technology turns that premise on its head, and with it many of the
deepest unstated assumptions about the function of a library.
Tracing back to Alexandria and before, the principal objective of
librarians has been to build the collection to amass a set
of materials was their measure of worth. But, in the future a library
will not "collect". Electronic information can be communicated
virtually instantaneously, so its source location is irrelevant.
Instead of a hoarder of containers, the library must either become
the facilitator of retrieval and dissemination, or be relegated to
the role of a museum.
If we project far enough into the future, it's not clear whether
there is a distinction between the library and the book. The
"technology" of the bibliographic citation pales by comparison to the
hypertextual link to the ability to gain immediate access to
the full referenced source, and hence to browse through the context
of the reference. It will take a long time to build the web, and
especially to incorporate the paper legacy, but the value of a
seamless mesh will doom the discrete, isolated volume.
As the library and the book merge, it seems compelling to me that
another merger will accompany it a merger precipitated by
devolving disciplinary boundaries. Knowledge isn't inherently
compartmentalized; there is only one nature, there is only one human
record. The division of the sciences into Physics, Chemistry, etc.,
and their further subdivision into Physical Chemistry is a human
imposition, as is the division into History, English and
Anthropology. For very practical reasons, paper texts have mirrored
this artificial division, but those "practical" reasons evaporate in
the electronic world. Clearly the "long pole in the tent" will be
human rather than technical; disciplines are complex and
idiosyncratic social structures that will not easily dissolve.
However and here I can only speak with the even the smallest
authority about technological disciplines much of the most
interesting work is already happening at the boundary of traditional
disciplines. That's not new news; Einstein opined that most of the
important science lay at the interstices of traditional disciplines.
What is new is that we have a technology that facilitates incremental
accretion of knowledge at these interstices.
Finally, note that the book as we know it is passive; they sit on
shelves waiting for us to read and interpret them. While there is an
intellectual thrill in discovery and interpretation, passivity of the
text is not required for that. As Marvin Minsky, a Professor at MIT,
said: "Can you imagine that they used to have libraries where the
books didn't talk to each other?". One of the profound changes in
store for libraries is that parts of their collection will be active,
software agents collecting, organizing, relating and summarizing on
behalf of their human authors. They will "spontaneously" become
deeper, richer, and more useful.
Teaching: The notion of computer-aided instruction has been touted
for thirty years. Frankly, it has had relatively little impact,
especially at the university level. The reason is obvious: chalk and
overhead projectors have been perfectly adequate technology given the
current nature of scholarship and texts.
If, however, the bulk of the Professoriate are using information
technology in their scholarship, and the results of that scholarship
can only be exhibited using the technology, the classroom will follow
rapidly. How will it follow? Not, I think, by the "automated drill"
scenario we have come to associate with Computer Aided Instruction,
CAI.
Beyond automated drill, the obvious application of technology is
telepresence the possibility of involving remotely sited
individuals in a seminar, for example. Again, do not think in terms
of today's teleconferencing technology; as the fidelity of
communication improves, telepresence will certainly happen. While
now it's a big deal to bring a leading authority to campus, and
access to the person is often limited to research colleagues and
graduate students, this will not be the case in the future. The
technology will give an increased number of undergraduates access to
these authorities. Removed from the overhead of travel, who among us
would not cherish a few hours each week with the bright young minds
at a remote Harvard or Yale?
These are interesting but mundane applications mundane in
the sense that they do not change the educational process in a deep
way.
More fundamental is the opportunity to involve students in the
process of scholarship rather than merely its results. We like to say
that we "teach students to think, not merely to learn rote facts",
but in truth
- we mostly limit them to thinking about what has been thought
before. We can't ask them to explore new hypotheses, because of
the practicalities of access to sources and the sheer grunt work
of collecting and analyzing data. Information technology
eliminates those "practicalities".
- they are forced through the linear sequence of the text,
course and curriculum before we judge that they "know enough"
(facts) to embark on a scholarly project (think).
A hint of this kind of change can be detected in a report in the
Chronicle of Higher Education about the impact of the release of
Thesaurus Linguæ Gaæce on scholarship and education in
the classics. The article noted that the release of this database,
which [now] includes virtually all Greek Literature from Homer
through the fall of Byzantium, has enabled undergraduate
participation in research.
One cannot leave the subject of teaching without at least mention
the subject of "productivity" the current code word to
capture the public's frustration with the rising cost of college
education and the perceived emphasis of research over teaching. Its
simplistic translation is to have professors spend more time in the
classroom and less in the laboratory. Particularly given the recent
wrenching restructuring of industry, the public has ample cause to
ask why an elitist academe should be exempt from a reorientation
toward greater customer satisfaction.
The irony, of course, is that one of the oldest figures of merit
for any school a low student/teacher ratio is
diametrically opposed to "productivity". Information technology is
not going to resolve this tension; in the end, for our own children
we want relatively individual attention from the most qualified,
intellectually alive professoriate possible. Information technology
can, however, shift the focus of the discussion to the effectiveness
and quality of the student/teacher interaction rather than just the
number of contact hours.
Indeed, in modest ways it already has shifted that focus. By
removing the barriers of both space and time for example, email has
given my students have much greater access to me than ever before.
Involving students in the process of scholarship and giving them
greater access to international authorities are more profound shifts,
but I suspect that these are still just pale precursors of what we
can do. Part and parcel of rethinking the impact of technology on the
university is addressing precisely this issue.
Let's return to the main thread. Whether or not you agree, I hope
that this discussion has at least suggested that activities in the
academy might change. Even so, that does not imply that the nature
of the university as a whole will change. Will it?
One approach to such a question is to examine unstated
assumptions; that's hard, but I would like to examine just one.
Historically a university has been a place. The stone walls of St.
Benedict's cloister at Monte Cassino were the bastion that provided
defense against the physical and intellectual vandals of the dark
ages. In colonial times, Jefferson's Academical Village provided
access to scholarly materials as well as collegial interaction by
collocation. In contemporary times, scholars flock to scientific
instruments and library collections. And, where the scholars
assembled, the students followed.
In his influential nineteenth-century essays on the Idea of a
University, Cardinal John Newman wrote :
If I were asked to describe ... what
a University was, I should draw my answer from its ancient
designation of a Stadium Generale ... This description implies the
assemblage of strangers from all parts in one spot.
The Cardinal then goes on at some length to emphasize that books
were an inadequate source of true education that must be buttressed
with discourse which is obviously only feasible if the
discussants are collocated. Thus the notion of being "in one spot"
is, to him, essential to the very definition of the university; as he
says, "... else, how can there be any school at all?"
But, with the possible exception of teaching, to which I'll return
in a moment, I believe that information technology obviates the need
for the university to be a place.
Once again, please remember that although we are presuming
technology better and cheaper than today's, it is not
hypothetical the trends are clear, the capabilities for at
least the next decade are predictable, and in many cases the
technology is already in the laboratory. Only how we will use the
technology is at question.
With this powerful, ubiquitous computing and networking, I believe
that each of the university's functions can be distributed in space,
and possibly in time. Remote scholarship and authoring are the direct
analogs of telecommuting in the business world, and every bit as
appealing. Academics tend to identify more closely with their
disciplinary and intellectual colleagues than with their university.
Freed from the need to be physically present in classroom, laboratory
or library, grouping by intellectual affinity may be more appealing.
But even then, physical grouping may be unnecessary and even
undesirable as such things as location preference are taken into
account.
There are some disciplines that need shared physical facilities,
say a telescope, that suggest the need of a "place". But note that
large scientific instruments such as telescopes and accelerators are
already run by consortia and shared by the faculty from many
universities, and many of these facilities do not require the
physical presence of the investigator they could be "on
line" and accessible via the network. Indeed some instruments, such
as those for space physics at Sondre Stomfjord in Greenland, are
already accessed on the Internet. The university as "place" is
already irrelevant to at least some scientific scholarship.
As with instruments in the sciences, direct access to archival
materials is necessary for some humanistic scholarship but
hardly all, and certainly not all of the time. Ponder the excitement,
for example, caused by the recent release of the images of the Dead
Sea Scrolls even though the scrolls themselves are not accessible to
most scholars. If anything, the ubiquitous information infrastructure
will provide greater access to archival materials to a much larger
set of scholars, of a quality that's "good enough" for most purposes.
As for teaching, we don't really know whether it can be
distributed or not. I do know that even asking the question is
considered heretical by some good teachers teachers who
contend that physical eyeball-to-eyeball contact is necessary.
Others, including me, contend although they need feedback to teach
well, there is a threshold of fidelity beyond which one does not need
to go; student and teacher probably don't need to smell each other,
for example. Thus, there is some finite amount of information
required to produce an adequate representation of the parties. If
true, when that threshold of fidelity is reached electronically, high
quality teaching will be distributed. The fallacy in Cardinal
Newman's reasoning was only that he could not imagine quality
discourse at a distance but that is precisely what the
technology will enable.
Can an institution such as universities that have existed for
millennia icons of our social fabric disappear in a
few decades because of technology? Of course; if you doubt it, check
on the state of the family farm. Will the "university as place" in
particular disappear? I expect not; the reduced importance of place
does not imply no place. However, just as farming has been
transformed, so will the university. The everyday life of both
faculty and students will be very different.
I have more questions than answers as to the new shape of the new
university. Having now laid the groundwork, let me pose a few of
them:
- I believe that higher education will not only survive, it will
flourish. But, are the choices for universities, like for Hans, to
become mass market manufactures or distributors, or niche tutors
to the privileged?
- Does it really make sense for every university to support the
full complement of disciplines, or should they specialize and
share courses in cyberspace? This might be a natural consequence
of aggregation by disciplinary affinity, for example.
- Might professors affiliate with several institutions, or
become "free lance" tutors to telepresent students? Indeed, might
we return to the future of tele-itinerant scholar/tutors?
- Might some employers (and hence students) prefer a transcript
that lists with whom certain courses have been taken rather than
where? Presumably a student that has taken a computer architecture
course from Patterson (at Berkeley) and a compiler course from
Kennedy (at Rice) would at least appear to be better trained than
one that took all their courses at just one of these fine schools.
- What about alumni and sports? Surely the allegiance of alumni
to their alma mater has a great deal to do with place and is
cemented on Fall weekends; since the support of alumni is
essential to universities, isn't that very human need sufficient
to perpetuate university as place? Perhaps. But broad alumni
support has become essential to the university only in relatively
recent times. Moreover, alumni associations and large sports
programs were created to support the university as place, not the
other way around.
- Will universities merge into larger units as the corporate
world has done, or will the opposite happen? I can argue either
side of this question. On the one hand, if a university isn't
(just) a place, its major remaining function is certification
it certifies the competence of the faculty, programs and
graduates. We don't need thousands of organizations to do that. On
the other hand, I can envision many small colleges being empowered
to provide a broad curriculum via telelocation while retaining the
intimacy so valued in our small liberal arts institutions. I don't
know anyone that really wants the impersonal ambiance of a
mega-university. The current size of these universities seems
optimized for the physical infrastructure, not either education or
scholarship.
- Might the technology revive the talented amateur's
participation in the scientific community? Except for a few
disciplines like astronomy, the talented amateur has largely
disappeared from scholarly discourse in science and engineering.
Surely such individuals still exist, but they are isolated from
the community of scholars. How can/should the university re-engage
them?
- What about the various businesses that have affiliated with
universities the university press being an especially
poignant example? My guess is that each of these will be forced to
rethink its principal mission, and many will be irrelevant.
- Will more (most?) universities serve a global clientele, and
how does that square with the publicly supported university in the
US? In particular, will private universities have greater
flexibility to adapt to globalization, thus dooming the public
universities?
- Does the function of socializing young adults, which perhaps
remains a reason for "place", need to be coupled with the
educational function, or could it be done better by some form of
social service?
Some will interpret these questions as threatening; I don't. That
there will be a change seems inevitable. But, change always implies
opportunity, and in this case the opportunity to improve all facets
of what we do in the academy. The challenge is to anticipate and
exploit the changes.
Universities are in the information business, and the information
railroad is coming.
