The Genomic Gutenberg Project – Writing the Living Novels of the Future

Decoding the over 3 billion DNA base pairs comprising the human genome was a monumental scientific/engineering achievement. Learning to read genomes was only the beginning and leading scientists propose it is time to develop the capacity to literally write them (1). Pushing far beyond today’s limits The Human Genome Project-Write will develop the ways and means to manufacture large DNA molecules and edit genomes with them. One of the ultimate goals is to synthesize the complete genetic code of any organism, including humans. There seems little doubt the spin-off technologies from the project will be transformative and will almost certainly foster an avalanche of new discoveries in many fields.
It is impossible to envision the full implications of this audacious proposal, but many scientists are in a total tizzy over the amazing prospects. However, past experience with emerging technologies reminds us there is no certainty every grand vision will come to pass or each idea proposed will be achievable. Many years ago futurists speculated every home would have mini atomic reactors to generate power and nuclear-fueled vacuum cleaners to help with the housework (2, 3). Today’s reality – utility companies determined to strangle the rooftop solar industry. Ideas like deleting potentially dangerous prions (1) seem solid at first glance, but no one knows what function(s) are performed by these genes. Could eliminating selfish DNA elements (1) change the ways genes are grouped and controlled in living cells and accidentally promote cancer induction (4)? The unknowns are numerous, but potential complications do not constitute a compelling case to halt the new research initiative. On the contrary, investigating and understanding them will improve understanding of basic cell biology which might ultimately yield important benefits for human health and wellbeing.
Controversy has been a feature of genomic synthesis work since viral chromosome construction projects generated concerns years ago (5, 6). Techniques have advanced enormously since the first small viral genomes were assembled, suggesting how fast
capabilities might evolve if The Human Genome Project-Write is approved (7). However, a public storm erupted before the proposal had been outlined (8) with thorny ethical questions and troubling scenarios cropping up immediately (8, 9). Would someone synthesize Einstein’s genome? How would such a thing be used? Extrapolating further, might researchers attempt to stitch together an artificially reconstituted Albert Einstein? In fairness, no one has proposed anything that extreme. In addition, proposals along these lines appear ill-considered. Human beings may not be a true tabula rasa at birth, but environment, education, culture and life experience all play critical roles in development. It might be technically feasible to duplicate genomes, but it still may never be possible to reproduce persons. Fiction readers may remember how the nature-nurture idea was explored by Ira Levin in The Boys from Brazil(10).
While many ethical and safety issues concerns raised over The Human Genome Project-Write are hypothetical, it is important to recognize the era of human-constructed life has begun. Despite daunting technical obstacles, scientists have created and cultured the first artificial bacteria (11). This synthetic life form has no living analogs, no true evolutionary kin and no known natural ecological niche, but Dr. Venter’s genomic creative writing group has proven it is possible to compose a total biologic fiction that actually works. They built the thing, but the scientist/creators are not omniscient and do not know what functions are performed by about one third of the genes in their handiwork (11). Having raced into unknown territory they must now wait to see if these new living fabrications adhere to their own private, unpredictable rules. One book of life has been re-written and there is something new under the sun. The problem is no one is quite sure what this thing will do.
The Human Genome Project-Write might be the 21st century genetic equivalent of invention of the movable type printing press by Johannes Gutenberg. The groundbreaking accomplishments of today only hint at the forthcoming not-of-this-natural-world fictions when future scientific Shakespeares are empowered to publish their own living novels.
