Though purists point out that cybernetics specifically refer to electronic, inorganic implants that interface with bodily functions, the term has come to mean any bodily implant that enhances biological function. These breakdown into cyberware (sometimes called hardware), which contains inorganic compounds, and bioware (wetware) that typically involved vat-grown organic material. It is rare, however to find cybernetics that don’t contain a bit of both.
The general wisdom is that hardware is more durable while wetware is more adaptable. Hardware is susceptible to EMP and other forms of electrical overload whereas wetware typically has some capacity for self-repair.
Wetware is also understood to be far more expensive and typically requires more skill than a streetdoc has to install. Hardware is less efficient overall but, much easier to install and replace.
