Nanotech future: goodbye poverty; hello healthier, longer
lives
By Dick Pelletier
Whether you fear it, welcome it, or think it's too crazy to
be true, this most publicized science of all time promises a
utopian future with a scarcity-free lifestyle for everyone on
the planet, and healthcare miracles that could extend lifespan
to the edge of immortality.
To achieve this remarkable future, researchers must first
create a tiny robot assembler that can grab individual atoms and
molecules and organize them into items. Futurists at the
Center for Responsible Nanotechnology believe that this
nanotech breakthrough could be realized by as early as 2020.
The next step is to build a Star Trek-like
replicator machine called a nanofactory with billions of
assemblers inside. This machine, which experts believe could be
created by mid-2020s, will sit on countertops and make products
similar to the way that life creates its miracles.
Guided by Internet-delivered software, robot assemblers will
pull atoms from supplied chemicals, or eventually, something as
inexpensive as dirt, air, and water; then reposition those
atoms, turning them into clothing, medicine, appliances,
tonight's dinner; or even another nanofactory.
Nanofactories could provide nearly all living essentials at
little or no cost. Even people in third world nations living in
remote locations will have access to this science as this
versatile machine can be instructed to replicate inexpensive
copies of itself.
In their book, Revolutionary Wealth, Alvin and Heidi
Toffler argue that we are on the verge of a post-scarcity time
that will alleviate most of today's poverty. In an online essay,
futurist Steve Burgess predicts that by 2025, nanoreplicators
will launch an unprecedented era of abundance.
Perhaps the boldest application of nanotechnology lies in
healthcare. Most sickness, injury and stress can be traced to
cellular malfunction. Current medicine does not allow doctors to
treat selective cells.
Today's medical solutions focus on treatments that often
include negative side effects. Surgery saves lives, but it also
causes trauma. Chemotherapy destroys cancer, but healthy cells
die in the process; and far too often, the cancer returns.
Enter nanotech. In clinical trials, doctors are injecting
nanoparticles that seek out only cancer cells and destroy them
without harming other tissues. In fact, the potential of
nanotech encouraged a former National Cancer Institute
director to challenge the group to eliminate all deaths from
this dreaded disease by 2015.
Later in this decade, nanomaterials will create lattices
allowing stem cells to grow new body parts to replace aging and
worn organs, bone, muscles, and skin. This will enable many
older people to recapture their youthful form.
At a recent conference, Pursuing the Longevity Dividend,
anti-aging scientist Jay Olshansky said that "humanity is about
to experience radical changes in medical technology, which will
provide healthier and longer lives for everyone."
Other nanomarvels include solar cells printed on Saran
Wrap-like rolls, which by 2015, will convert rooftops into power
generators. By 2020, nanomaterials will analyze vitals and
display information on the skin like a temporary tattoo.
By 2030, nanobots will visit every cell in our body to
maintain perfect health and finally bring an end to humanity's
greatest scourge – aging. Welcome to immortality!
Can this incredible "magical future" unfold in such a rapid
timescale? Positive futurists believe that it can.
