The author's assumption is that artificial (non-sexual) reproduction will eventually be SUPERIOR -- safer, cheaper, faster, more predictable, less painful, etc.

The author's assumption is that artificial (non-sexual) reproduction will eventually be SUPERIOR -- safer, cheaper, faster, more predictable, less painful, etc. -- because unlike sexual reproduction, it benefits from exponential advances in technology. The author therefore predicts that more and more people, and women in particular, will prefer it in the future.
