The phrase “designer babies” bundles several scientific and ethical questions into one dramatic image. It can make treatment, experimentation, and selecting desired traits sound like variations of a single consumer service. Understanding the distinctions is the first step toward a useful conversation.
The World Health Organization's overview of human genome editing distinguishes somatic changes, which are not inherited, from work involving germline cells and from heritable editing that could affect descendants. Those categories change who may experience the consequences and what kind of oversight is needed.

Calling DNA “code” can help introduce the idea of stored biological information. It can also suggest that changing a sequence is like changing a character setting in a game. A human trait is not necessarily a single switch with a predictable, isolated effect.
That matters when discussing what should be permitted. A proposal aimed at preventing a serious condition raises questions about evidence, alternatives, consent, and uncertainty. A proposal aimed at meeting a social ideal raises further questions about who defines that ideal and who could access the intervention.
Watch for moments when the discussion moves from what researchers can change to what people should choose. Those are related but different arguments. The technology cannot make the ethical decision for us, and a striking headline should not substitute for understanding the particular intervention being proposed.
