Thoughts on the (so far) overhype of genetic sequencing.
I think that there are going to be huge breakthroughs in health and longevity, but our understanding of genetics is currently much too dismal for them to come from DNA analysis in the near term.
My understanding is that the DNA is a recipe, not a blueprint. And while even with a blueprint of a house, the final product is still dependent on the carpenter, it is at least specified. A recipe can have much more varied outcomes, depending on the cook, and the available resources and ingredients.
