Intimate knowledge can become leverage.
Intelligent Agents can learn our habits, relationships, fears, interests, routines, vulnerabilities, and private thoughts through what we tell them and how we behave around them. Knowledge that helps a system understand us can also make us easier to predict and influence.
An Agent that knows us can help without owning what it knows.
Memory and context can make an Agent genuinely useful: helping with daily life, recognizing a need, finding support, coordinating plans, and carrying our intentions across tasks, while personal information remains bounded by rules designed around the person rather than the platform.
