Seriously. I have kids, so my genes have been passed on, but what's so special about only my genes passing to the next generation? Why should I have a problem with having the product of our minds carry on our legacy? what if we could create a galactic empire made by our descendants, where our descendants are not biological but the products of our minds? That idea seems to me amazing and worthy!
I doubt that if AI ever took over it will get rid of biological life, but if it does, so what? other species have gone extinct, we will too. AI may be the worst event in the history of **our** civilization, but the best event in the history of **it's** civilization!
