Wouldn't it be simpler to say "put 10^80 hydrogen atoms really close to each other and wait a few billion years". Simpler, and just as useless (insofar as it doesn't get anyone closer to simulating a brain in the next 10 years).
The human genome, on the other hand, succeeds in growing intelligent brains a more or less measurable fraction of the time, in only a couple of years: at least 5%, if we assume that 94.9% or so of all zygotes fail to implant or otherwise miscarry, and another 0.1% suffer some kind of disability that forecloses the development of intelligence.
This is observably different from the development of most similar-sized chunks of matter, even biological tissue, over similar timescales. For example, my body has contained about 100kg of biological tissue for the past 15 years. That's enough time for each 10kg chunk of it to develop intelligence about 7 times. But I'm not aware of any new intelligent entities in my body during that time. Some might doubt the existence of any intelligent entities in my body at all.
Well, no, of curse you wouldn't be. Insensitive clod.
