Who says that the drugging Watsons are the only working component in the system? I think the far-reaching effect of this not-that-unlikely szenario has the potential to make many other failure modes much more likely. A self-satisfied society has much less energy to detect them for example. A more complex system makes failure modes more numerous.

Did you know about this?

DARPA SUBNETS

The SUBNETS vision is distinct from current therapeutic approaches in that it seeks to create an implanted, closed-loop diagnostic and therapeutic system for treating, and possibly even curing, neuropsychological illness. That vision is premised on the understanding that brain function—and dysfunction, in the case of neuropsychological illness—plays out across distributed neural systems, as opposed to being strictly relegated to distinct anatomical regions of the brain. The program also aims to take advantage of neural plasticity, a feature of the brain by which the organ’s anatomy and physiology alter over time to support normal brain function.

Sounds pretty straightforwardly like programming a brain.
