In her book "Future Superhuman: Our transhuman lives in a make or break century" Elise Bohan doesn't agree with you on this issue. Why bother with complicated, imperfect, ageing & failing humans when you can have a perfect, never complaining, fully understanding robot? An AI that really understands you and has access to all your data since you were born. Her idea not mine:).

So life in a an absolute perfect bubble. The ideal echo chamber. Well, at least the good news is that it will radically reduce procreation. Less humans, less pressure on our environment and more space for other life forms.
