Superintelligence:
Paths, Dangers, Strategies is a 2014 book by the philosopher Nick
Bostrom. It explores how superintelligence could
be created and what its features and motivations might be. It argues that
superintelligence, if created, would be difficult to control, and that it could
take over the world in order to accomplish its goals. The book also presents
strategies to help make superintelligences whose goals benefit humanity. It
was particularly influential for raising concerns about existential risk
from artificial intelligence.
Synopsis
It is
unknown whether human-level artificial intelligence will arrive in
a matter of years, later this century, or not until future centuries.
Regardless of the initial timescale, once human-level machine intelligence is
developed, a "superintelligent" system that "greatly exceeds the
cognitive performance of humans in virtually all domains of interest"
would most likely follow surprisingly quickly. Such a superintelligence would
be very difficult to control.
While the
ultimate goals of superintelligences could vary greatly, a functional
superintelligence will spontaneously generate, as natural subgoals, "instrumental goals" such as
self-preservation and goal-content integrity, cognitive enhancement, and
resource acquisition. For example, an agent whose sole final goal is to solve
the Riemann hypothesis (a famous unsolved
mathematical conjecture) could create and act upon a subgoal of
transforming the entire Earth into some form of computronium (hypothetical
material optimized for computation) to assist in the calculation. The
superintelligence would proactively resist any outside attempts to turn the
superintelligence off or otherwise prevent its subgoal completion. In order to
prevent such an existential catastrophe, it is necessary to
successfully solve the "AI control problem" for the first
superintelligence. The solution might involve instilling the superintelligence
with goals that are compatible with human survival and well-being. Solving the
control problem is surprisingly difficult because most goals, when translated
into machine-implementable code, lead to unforeseen and undesirable
consequences.
The owl on
the book cover alludes to an analogy which Bostrom calls the "Unfinished
Fable of the Sparrows". A
group of sparrows decide to find an owl chick and raise it as their servant.They
eagerly imagine "how easy life would be" if they had an owl to help
build their nests, to defend the sparrows and to free them for a life of
leisure. The sparrows start the difficult search for an owl egg; only
"Scronkfinkle", a "one-eyed sparrow with a fretful
temperament", suggests thinking about the complicated question of how to
tame the owl before bringing it "into our midst". The other sparrows
demur; the search for an owl egg will already be hard enough on its own:
"Why not get the owl first and work out the fine details later?"
Bostrom states that "It is not known how the story ends", but he
dedicates his book to Scronkfinkle.
Reception
The book
ranked #17 on The New York Times list of best selling science
books for August 2014. In the same month, business
magnate Elon Musk made headlines by agreeing with the book
that artificial intelligence is potentially more dangerous than nuclear
weapons. Bostrom's work on superintelligence has
also influenced Bill Gates's concern for the existential risks facing
humanity over the coming century. In a March 2015 interview by Baidu's CEO, Robin Li,
Gates said that he would "highly recommend" Superintelligence.
According to the New Yorker, philosophers Peter
Singer and Derek Parfit "received it as a work of
importance". Sam Altman wrote in 2015 that the book is the best
thing he has ever read on AI risks.
The science
editor of the Financial Times found that Bostrom's
writing "sometimes veers into opaque language that betrays his background
as a philosophy professor" but convincingly demonstrates that the risk
from superintelligence is large enough that society should start thinking now
about ways to endow future machine intelligence with positive values. A review in The
Guardian pointed out that "even the most sophisticated
machines created so far are intelligent in only a limited sense" and that
"expectations that AI would soon overtake human intelligence were first
dashed in the 1960s", but the review finds common ground with Bostrom in
advising that "one would be ill-advised to dismiss the possibility
altogether".
Some of
Bostrom's colleagues suggest that nuclear
war presents a greater threat to humanity than superintelligence, as
does the future prospect of the weaponisation of nanotechnology and biotechnology. The
Economist stated that "Bostrom is forced to spend much of the
book discussing speculations built upon plausible conjecture... but the book is
nonetheless valuable. The implications of introducing a second intelligent
species onto Earth are far-reaching enough to deserve hard thinking, even if
the prospect of actually doing so seems remote. Ronald Bailey wrote in the
libertarian Reason that Bostrom makes a strong case
that solving the AI control problem is the "essential task of our
age" According to Tom
Chivers of The Daily Telegraph, the book is difficult
to read but nonetheless rewarding. A
reviewer in the Journal
of Experimental & Theoretical Artificial Intelligence broke
with others by stating the book's "writing style is clear" and
praised the book for avoiding "overly technical jargon". A
reviewer in Philosophy judged Superintelligence to
be "more realistic" than Ray Kurzweil's The Singularity Is Near.
