Do we really need caveman-capabilities? To be ready for the day we lose our tech and have to start over?

In a different context it has been discussed how we have used up our easily accessible energy and may not be able to restart civilization on this planet. So why keep lowtech genes around? Make way for large brains and large heads!

I think maybe in the back of everyone's mind is the post-apocalyptic scenario. Which is strange, because at at that point we'd have far greater worries, such as lack of food, clean water and antibiotics.

State/government-dependence to give birth is a worry!
