“Designer babies” refer to children whose genes are selected or edited before birth to produce desired traits—such as intelligence, athleticism, or eye color. With CRISPR and other gene-editing tools, this once sci-fi concept is inching closer to reality.

In theory, genetic editing could eliminate hereditary diseases and enhance future generations. Parents could choose to remove harmful mutations or even boost immunity, intelligence, or height. The first known gene-edited babies were born in China in 2018, igniting global controversy.

Supporters argue that we already make choices for our children—why not genetic ones, especially if it means better health? But critics warn of a slippery slope toward eugenics and inequality. Could designer babies become a luxury only the wealthy can afford?

There's also concern about unintended consequences. Editing one gene might disrupt others, leading to unknown side effects passed down for generations.

Laws and regulations differ worldwide, and international consensus is still forming. Most scientists agree that while curing genetic disease may be acceptable, enhancing traits purely for preference raises serious ethical red flags.

The idea of designer babies forces us to confront what it means to improve humanity—and who gets to decide.
