My own feeling is that we know enough about the mathematics of complex systems to be very wary of simplistic models of how genes act, and this feeling is reinforced by the huge amount that we don’t know about genes. I wouldn’t trust a computer whose software had been hacked by a bright ten-year-old, even if the result gave me a really nice screen saver. I would worry whether anything had accidentally been damaged when the program was hacked. I would be more likely to trust a professional programmer who really understood the computer’s operating system. But right now, genetic engineers are really just clever hackers, and no one has much idea of how the genetic ‘operating system’ really works.
