> Biological brains have had a few billion years to optimize.

Not just that, but it's grown on a body which has been optimized for survival during a few billion years; and that body is built on cells that have evolved to survive hostile environments, and those cells are built with self-replicating molecules, evolving from complex chemical reactions in several changing environments, that competed with and displaced other less-successful self-replicating molecules that disappeared.

Each of those layers provides a degree of adaptability and self-healing that is extremely hard to replicate. And if we managed to reverse-engineer and replicate one of those layers, it would still be missing all the layers below.

Our best hope to create fully independent agents will come from re-adapting and controlling biological entities, not from tools built from the ground up with current engineering techniques.
