Impressive, awe inspiring and beautiful. The ancient struggle between liberalism utopia ("He has hidden himself at the end, as far from the tidal flats and the beginning as he could find) and nihilistic darwinism, told by the means of mythical proportions. As it should be. Religious and mythical grammar speaking current philosophical transhumanist questions. A tad presumptuous " for it is a wonder to her to be named so well by something so small.", but efficient. Darwinian evolution is ultimately defeated by what it creates. The story reeks and swims within paradoxes and contradictions.
I was, however, a bit confused by the last parts of it.
