ISTM that Genetic engineering today is comparable to the technology of Fire back in the stone age somewheres.

We can see it happening naturally, and direct it a little with breeding. We've just recently discovered how to start our own in a very rough manner by rubbing sticks and scraping flint.
We've got a long way to go before we can make the steam engine of genetics, and like fire, it will have its dangers long past the time when we do have fine control.
