The human genome project was completed over two years ago and that means that we are able to read the blueprint for the human machine.
We have the blueprint, we are still learning to read it, and once that has been accomplished we will be able to write into it. Every time there is a new patent based on a human gene thats a signal that more of our "gene language" has been learned.
