The Race To $1,000 Human Genome Sequencing

It's worth pointing out that it's not just human genomes which will be cheap. I'm excited about the applications this has in biology at large. If sequencing costs continue dropping at anything like their current rate of decrease, whole genome sequencing will soon be opened up to all sorts of interested parties. That has huge implications for taxonomy and phylogenetics, conservation, crop breeding and plant science as a whole.

If genome sequencing costs drop, that means other types of sequencing costs drop too. For example RNA-Seq, which lets us see which genes are currently active at a given point in time, in a sample from an organism. Things which are currently conceptually possible but prohibitively expensive, such as comparing the active genes across hundreds or thousands or species in a particular state, or across a species in hundreds of different environmental conditions, will become possible. Our understanding of life processes will deepen by an order of magnitude, with inevitable benefits in biotech, medicine and agriculture.
