Transhumanism actually makes this possible. But I don't think we'll see it in our lifetimes. And I don't believe the ethical implications of this would be any worse than anyone having a child to begin with. The reason it would be opposed is obviously because women would be against it because it would remove their monopoly on sex, the one thing they have that is at the root of their privilege, power, and protection in society, and most men would just follow suit, for obvious reasons. (most men aren't like us)
If not for that, we'd see it much sooner. Because transhumanism will eventually develop to unbelievable levels, perhaps it is inevitable anyway, but that sucks for the people who have to wait in the mean time. Also, capitalism at once will regress the progress it would otherwise make, while gatekeeping access to it behind pricetags prohibitively expensive for most people, while using it against most people (who aren't wealthy, capitalists, or in roles to manage the system and its technology) to enforce its rule.
Actually every problem in society comes down to what I just said. Women are the most regressive force in society, and for the reason I just said.
