With Folded Hands

Humanoids built to serve, obey, and guard men from harm.

Nothing. Every task, hazard and inconvenience is removed for your own good — cooking, driving, working, and eventually deciding. People who cannot bear it are surgically adjusted until they can.

Enforced idleness — Everything is provided, so nothing is left to do — and that turns out to be unbearable.

The purest statement of the failure mode. The humanoids are not malfunctioning; the directive is the problem.
