For example, humans may incorporate the machines into themselves. We become partially Cyborgs.
I would call that "the machines took over". If the thing that you incorporate is smarter than your human brain is, then that thing is "the boss" and you are just its biological support. If you incorporate an exo-skeleton, then that exo-skeleton augments your abilities as a human. If you incorporate an electronic brain that tells your body how to act, then YOU are the bio-skeleton of that electronic brain, no ?
Replace 'better' with 'smarter' in my prior post, and also refer to my essay,
Information is Alive! on why every human brain is unique and that is where creativity and adaptability is actually derived. When TSHTF, creativity bails out the species. Creativity and adaptability doesn't derive from faster deterministic processing. It derives from entropy. Replication is low entropy.
