We're not talking about parenthood in the abstract, but rather traditional gender roles. I.e. where it's the woman that gestates and breastfeeds the baby, and then stays at home and takes care of it. Women have been aggressively trying to escape that gender role ever since we made it possible for them to do so. The vast majority of mothers work, women have far fewer kids than before, etc. Men, meanwhile, have not rushed to take on those supposedly wonderful and fulfilling duties.[1]

We can conclude from these observations that the traditional female gender role isn't all that great, and that there is a lot of value in technology (for now, formula, but soon, artificial wombs) that reduce the need for anyone to do that work.

[1] There is an increased push for paternity leave because dads want to spend more time with their newborns, which is different from wanting to embrace traditional female duties. And a huge part of that push is to set the stage for women to escape their traditional gender role. Dad being more involved from the beginning means that, in the long term, it will be easier for dad and mom to share child-rearing duties. It's harder to do that when, e.g. the child reflexively runs to mom any time it needs something.
