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

Nor should there be any. Personally, I would've prefered growing up in a society where the family model was non-existent. Don't just stop at births, remove the "parents" altogether. And that's regardless of how happy I would've been otherwise.

The traditional family model works fairly well.

Parents have a high level of motivation to look after their own contribution to the gene pool, children are benefited psychologically by contact and bonding in general with the parents.  

I don't understand why there shouldn't be any bond with the parents like you're suggesting.

People can be motivated to look after kids, in general. Everyone can be a parent in the society I envision. Responsibly, even. Kids could be very well taken care of as far as their physical needs are concerned and get their role models and everything else from Janes and Joes Doe.

If this sort of thing concerns you, I also see us heading into a society where surveillance becomes so ubiquitous that it becomes a natural part of our lives instead of a thing of concern. Society will undergo extreme changes because of radical new technologies, anyway. All I can do is guess at what those changes might be, I can't say which will turn out to be right, though, if any, just that change itself will happen no matter what.

I feel like absent of two absolute figures a child can grow up much faster and become a much more responsible and liberated individual.
