God does not play dice. Evolution does. For now
Transhumanism will be more than a mere improvement of man through technology; it is going to bring an end to evolutionary randomness, the fundamental principle which (coupled with natural selection) has driven the evolution of all organisms since the emergence of life on Earth (and quite possibly anywhere else in the Universe). Our genetic materials, like those of every living being, undergo minute arbitrary variations as they are being replicated; some are detrimental, some have no effect whatsoever, and others give the next generation’s organism a slight competitive advantage in the game of natural selection, yielding a higher probability that they will in turn propagate to its offspring.
While this process has been greatly effective at turning the early single cell prokaryotes into homo sapiens sapiens (among other species) and at giving rise to emerging properties such as sentience, culture or politics, it has also been very inefficient – being both extremely slow (3.5 billion years since abiogenesis, or the emergence of life from inanimate amino acids) and extraordinarily wasteful (only a fraction of the random genetic mutations are beneficial to the offspring, leading to the unnecessary death of countless organisms for the improvement of one).
As our mastering of technology grows exponentially, we will become increasingly capable of directing evolution in a way that is both effective and efficient. Our intelligence will allow us to engineer our own evolution (choosing which improvements, both mental and physical, we should bestow upon ourselves) and technology will allow us to execute it at a pace and an accuracy orders of magnitude higher than random evolution.
As a final digression, it is amusing to note that creationists could have been inadvertently having a point when talking about intelligent design – not that it has existed at any point in the past in some magical fashion, but in the way that it is likely to be part of our future and be driven by man himself. With the advent of transhumanism, we will essentially become the masters of our own evolution as a species, taking over a role traditionally assumed by deities; thus ushering in an era of post-theism, the next stage of mankind’s spiritual development that does away with the mental crutches of faith and religion.
