MIT Technology Review on the incredible rise in number of genomes sequenced per year:
Exponential: The number of human beings whose entire DNA sequence is known has increased dramatically.
This year, the world’s DNA-sequencing machines are expected to churn out 30,000 entire human genomes, according to estimates in Nature magazine. That is up from 2,700 last year and a few dozen in 2009. Recall that merely a decade ago, before the completion of the Human Genome Project, the number was zero. At this exponential pace, by 2020 it may be feasible—mathematically, at least—to decode the DNA of every member of humanity in a single 12-month stretch.
The vast increase in DNA data is occurring because of dazzling advances in sequencing technology. What cost hundreds of millions of dollars a decade ago now costs a mere $10,000. In a few years, decoding a person’s DNA might cost $100 or even less.
