I think this is an interesting issue which will probably become more affordable in future. Biology obviously constrains the age at which women can currently have birth, but this could theoretically allow women to have children at a much older age. You could also argue that men should freeze sperm as the incidence of de novo mutations in children increases with paternal age.
It's also a way of equalising a disadvantage women have to some extent, in that they spend their prime fertiity years getting a degree or working. As the author notes:

Women have enjoyed more opportunity in nearly every area of their lives, except the ability to have children. We undoubtedly will be trying to navigate this mismatch for generations to come, but if technology can temporarily compensate by adding another layer of choice, that is a reprieve indeed.
