What is human enhancement?

Human enhancement uses technology to upgrade body and mind beyond what nature gave you. I predict wearables, implants, brain-computer interfaces (chips that connect your brain to a computer, the kind Elon Musk's Neuralink already puts in paralyzed patients), and biotech will boost physical ability, cognition, and health, while raising deep ethical questions. The line between treatment and enhancement blurs fast: a chip that lets a paralyzed man type is medicine, the same chip in a healthy stockbroker is an upgrade. The debate moves from whether we can to whether we should, and who gets access. That conversation cannot wait for the technology to arrive.
