The document discusses how technology is saving lives through advancements in prosthetics and modifying DNA. Prosthetics have become more comfortable and customizable, and some can now be controlled by the mind. Researchers are also using CRISPR gene editing technology to potentially cure diseases by cutting out bad genetic code. While this could cure illnesses, it raises concerns about designing superior babies. The future may see 3D printed prosthetics and curing conditions like cancer, HIV and Huntington's disease through DNA changes.
