Extending Biology
For 3.6 billion years, evolution has governed biology
on this planet; now Mother Nature has a collaborator.
Inexpensive tools for reading and rewriting the genetic
code of life are enabling us to manipulate biology from
the bottom up.
“The idea of synthetic biology is to do for biology
what electrical engineers have done for circuit design
and what chemists have done for the synthesis of
chemicals—that is, to make an engineering field out of
it,” says University of California, Berkeley, Professor
Jay Keasling, director of Lawrence Berkeley National
Laboratory’s Synthetic Biology Department. “Rather than
just use the natural devices as they exist, we’re
building new parts that we can integrate into devices
that function in predictable ways.”
Keasling is already developing microbial factories to
produce drugs against malaria and cancer and to spew out
octane for fuel. Meanwhile, MIT researchers are building
a storehouse of interchangeable parts—BioBricks—that can
be snapped together to construct artificial systems in
living cells. One key enabler behind synthetic biology
is the ability to rapidly sequence and synthesize DNA
and to do it very cheaply. Forty-two percent of our
respondents believe that it will become affordable to do
this for any organism in the next decade; another 38
percent think it will happen in the following decade.
What about sequencing your own genome? Fifty-six
percent of our respondents forecast that most
individuals in developed countries will have a
documented personal genetic profile within two decades.
“Medical therapies will be quite individualized,” Edward
Berbari, biomedical engineering professor at Indiana
University–Purdue University, Indianapolis, noted in his
survey response. “These will be specific therapies for
diagnosed maladies aimed at very specific metabolic
pathways.” He expects such therapies in another 10 years
or so.
New devices are on the horizon that would close the
gap between biology and bits. Cochlear implants to treat
deafness and deep brain stimulators to treat Parkinson’s
disease are already on the market. Meanwhile,
implantable brain-machine interfaces are making
headlines with primitive artificial vision systems and
mind-controlled robot prosthetics. But fewer than half
of the Fellows believe that implantable brain-machine
interfaces will be widely adopted.
“While technology may permit many of the forecasted
accomplishments to occur, human beings may well resist
their implementation,” writes electrical and computer
engineering professor Andrew Szeto of San Diego State
University in his survey comments.
As Yogi Berra reportedly said, “The hardest thing to
predict is the future.” And as we’ve said, our survey
does not try to predict the sci-tech future but merely
to uncover key directions. So although we may not be
able to say that in 2015 a space elevator will be
shuttling goods and people into orbit or that in 2020
we’ll all have robot servants, we can foresee that in
the next several decades we will be building our
infrastructure in a new way: we will have unlimited
computing resources, live in a sensory-rich computing
environment, and reengineer ourselves and the biological
world around us. Understanding these larger trends helps
organizations think about adapting to the future, and
thus shaping it. Alan Kay’s prescription: “The best way
to predict the future is to invent it.”
