The inability to trace DNA to actual diseases has serious consequences. As does the opposite problem - not being able to trace diseases back to DNA.

The most profound change that genetics brings about might not be scientific at all. It might be mental and even spiritual enrichment: a more expansive sense of who we humans are, existentially, and where we came from, and how we fit with other life on earth.

Even if we never cure a single disease, the Human Genome Project and other ventures will have been worth it.
