Enfeeblement is the human side of delegation. When a tool handles a task reliably, people stop practising it, and over time they lose the ability to check the tool or to do the task without it. Stuart Russell has said that humans in the long run do not want to be enfeebled, and conceded that he has no solution to the problem. He points to the film WALL-E as a future we do not want.
For an organisation the practical form is the loss of the ability to reverse a decision: the system works, the skilled people have moved on, and nobody can step in when it fails.
