They did not command the wealth of nations, these researchers. Although their grants amounted to millions of Euros, they could never have funded a deep-space mission on their own, nor could they have built the giant machineries they conceived of. In order to achieve their dream, they built their prototypes only in computer simulation, and paid to have a commercial power satellite boost the Wind seeds to a fraction of light speed. [...] no one expected the Winds to bloom and grow the way they ultimately did.

It is further explained that the Winds were designed to evolve on their own so they are not mere puppets of human intentions but possess their own intrinsic architecture.

In other places in the book it is explained how humans did not create their AI Gods but that they evolved themselves from seeds designed by humans.
