What are artificial wombs and what could they change?

Artificial wombs are machines that grow a baby outside the body, and they could reshape healthcare, fertility treatment, and neonatal care. Today the technology means a fluid-filled bag that keeps extremely premature babies alive, tested on lambs at the Children's Hospital of Philadelphia and now moving toward human trials. I predict that as it matures, it challenges deep assumptions about reproduction, family, and human development. It begins as a medical breakthrough for premature infants. Its longer-term implications for how humans reproduce rank among the most profound questions biotech will ever force us to answer. The pattern I warn about everywhere: the science sprints ahead of the ethics. Start thinking now, before the first company sells it as a lifestyle choice.
