Are we moving towards a ‘brave new world’? As scary as chip implants may sound, they form part of a natural evolution that wearables once underwent. Hearing aids or glasses no longer carry a stigma. They are accessories and are even considered a fashion item. Likewise, implants will evolve into a commodity. If that sounds unlikely, then consider the alternatives we currently use. Drugs often show unwanted effects because they affect multiple biological processes at the same time. Someone on long-term medication may want to try an implant that sends very precise electrical or optical pulses instead.
