There have always been hackers. If we look back 30 years to the earliest days of the personal computer, the first iteration were DIY types with cobbled-together devices, tinkering in garages and basements and meeting periodically to share their stories. Their intentions were mostly non-malicious: they hacked for fun and to learn what was possible. From these dabblers came the first generation of technology entrepreneurs, such as Steve Wozniak, Steve Jobs and Bill Gates.

A living cell is analogous to a computer, albeit a very sophisticated one, made of carbon rather than silicon. At its heart is an operating system. It's written in DNA nucleotides – chemical bits denoted in the less familiar As, Ts, Cs and Gs of DNA code – but, fundamentally, not so different from the zeroes and ones of electronic software.

Seen this way, cells are self-assembling, non-toxic, self-repairing, low-energy, infinitely scalable and adaptive computing devices. Moreover, even though life has evolved over billions of years and digital computers have been engineered for just a few decades, their fundamental architectures aren't all that different. Cells are hardware and DNA is software. The result?

Biology, like other forms of computing, can be hacked.

And it is being hacked, every day.

Personalized Bioweapons

In coming years it may be conceivable to design a pathogen that targets a specific person’s genome. This agent may spread through populations showing minimal or no symptoms, yet it would be fatal to the intended target (4).
