Why humanity destroyed itself

[quote=“Haystack, post:13, topic:94806”]My expectation is that technology will soon reach a point where we’re able to guide our own evolution through cybernetics, genetic engineering, etc. That dynamic will feed back on itself as the first generation of augmented humans influence the direction of future augmentation, so that it becomes really important who makes the first steps and why.
