In the future men will be able to carry children just like women

[Arkilogue]

I think the external development and delivery of the child would be highly detrimental to the bond a mother has with the child. The woman's body goes through massive hormonal change, nesting instincts kick in, and the moment of birth for all it's pain, is a major bonding moment as a cocktail flood of hormones rush in stimulating love and empathy as well as prepare the mothers body for breast feeding.

But I suppose they'll have a pill for all that.

Science will have to tell how many of these things can be overcome by technical means. Many children are already born via C-Section (as was ours, for urgent medical reasons, not as a choice), and indeed they do have a pill for what you mention, namely the above-mentioned oxytocin infusion. I myself, in my role of having been a mere onlooker, wasn't lacking any love and empathy either - our brains do that hormone stuff even without the direct physical contact, and how.

I was with my wife when she delivered as well and it was incredible, I was crying with joy.

But my point is the mothers body is pushed through this directly/hormonally throughout the pregnancy the father's is not. The mother is more prepared by nature, the father is more by will. That has been my experience and observation. Unless the father wills himself into the role, the males natural DNA impulse is to father another child with another woman. The woman's impulse is to take care of the child she birthed.

Hell, they should make a pill for the father!
It might help, but it would also be cheating.
