Your Definition
In a technological context, this extends beyond human pregnancy to describe any system, entity, or machine that acts as a substitute, vessel, or experiential proxy for another. This can range from a remote-controlled robot avatar (a "surrogate body") exploring a toxic environment, to an AI that serves as a legal or digital surrogate for a person in virtual meetings, to using engineered organisms as living factories to produce chemicals. It's the outsourcing of presence, risk, or biological function.
