== Summary ==
Engineered cells and biological circuits could sense disease, manufacture therapies, and adapt inside the body.

== Key takeaways ==
* Living therapies can sense and respond in ways static drugs cannot.
* Control systems, kill switches, and containment are core product features.
* The body is a noisy deployment environment, so robust behavior matters more than elegant diagrams.

== Mechanism ==
Synthetic biology designs genetic circuits, engineered cells, and biomolecular systems with defined inputs and outputs. In medicine, that could mean cells that detect inflammation, secrete proteins, or attack disease only under specific conditions.

The promise is local intelligence. Instead of dosing the entire body, a living system can operate at the site of need.

== Constraints ==
Engineered biology evolves, interacts, and sometimes fails in nonlinear ways. Safety architecture is therefore part of the therapy, not a regulatory afterthought.

For human augmentation, the question is whether a synthetic circuit improves resilience without creating unmanaged dependency or ecological risk.

== Watchlist ==
* Kill switches
* Immune escape
* Circuit drift
* Manufacturing reproducibility
