But if you pursue an evolution over millions of years, at some point we'll have to miniaturise. Imagine we can make fully conscious silicon - let's say in 200 000 years (6500 human generations). At this point, we'd be tempted little by little to raise them as our intellectual children and find less and less need to make them with sperm and vagina. After a long while, there might be this great replacement, totally peaceful, that would lead these conscious organisms with a vastly superior intellectual efficiency to probably become very small and self centered and not behave like the territorial monkeys we are. What do you think a massively singular electronic intelligence will think when it notices a planet like ours ? "nuke them all and rape their women" ? This is monkey behavior that we still haven't fully shaken up.
