Artificial Life creations will revolutionize our world
By Dick Pelletier
Say goodbye to global warming, toxic waste, and dependency
on fossil fuels; and get ready to enjoy perfect health with
exotic drugs that could one day cure every human disease,
including aging. These are just some of the possibilities
researchers envision as they attempt to copy how nature gathers
non-living matter and transforms it into life.
Life is generally not thought of as being mechanical, but a
cell basically is a miniature machine which rearranges
non-living atoms to create parts that "bring it to life."
Genetic pioneer Craig Venter predicts that the first artificial
life form will be a simple bacterium that proves the technology
works, which he expects to see later this year.
This breakthrough will then be followed by more complex
bacteria that can turn coal into clean natural gas, create algae
that can soak up carbon dioxide and convert it into fuels, and
develop low-cost drugs that will help doctors achieve a
healthier and longer lifespan for everyone.
Exxon Mobil recently signed a $600-million project with Dr.
Venter's Synthetic Genomics to make biofuel from algae.
Executives predict that this venture could lower our dependency
on oil, clean up environmental pollution, and reduce global
warming.
"Creating artificial life has the potential to shed new light
on our place in the universe," says Mark Bedau, COO of ProtoLife
in Venice, Italy. This amazing breakthrough will remove the
fundamental mystery about human creation and our role in the
world, he said.
Although most people see this technology as providing mankind
with virtually unlimited commercial and medical benefits, others
worry about the ethical and moral issues of human-made life.
"The first artificial life form is likely to shock people's
religious and cultural beliefs," said Bedau.
It's true, we are tinkering with something very powerful, adds
Steen Rasmussen of the NASA-supported Protocell project at Los
Alamos National Labs, "but there's no difference in what we're
doing here and what humans did when they invented fire, designed
the transistor and split the atom," he said.
Harvard Nobel Laureate Jack Szostak predicts his lab will create an
artificial cell-housing within the next couple of years, and by
2015, develop nucleotides to form a complete cellular system. He
believes once this happens, Darwinian evolution will take over,
revealing how modern cells arose from their simpler ancestors.
This knowledge will help us understand how humans evolved in
the past, and provide guidance towards a future human evolution
driven, not by nature, but by tomorrow's technologies. We will
see tiny self-reproducing factories, disease-killing machines,
and exotic creations performing many useful functions. Experts
believe that by 2020, artificial life creations will eliminate,
or make manageable, most human diseases.
Could artificial life forms ever run amok and destroy our
world? "When these things are created, they'll be so weak, we'll
be lucky if they remain alive for an hour in the lab," Bedau
said. "Breaking out and taking over the world – never in our
wildest imagination could this happen – plus, potential
life-saving benefits of this technology are enormous."
Positive futurists predict that by mid-2020s, human-made life
forms will provide us with an affordable, ageless and forever
healthy body fashioned from newly-created ‘designer genes.' Go
"magical future."
