> It's not yet possible to get a hierarchical system to emerge from machine learning. Medium term planning as an emergent behavior is a near term big challenge for AI. It's also a big challenge for AI safety / Machine Ethics / Formal Verification. It's notoriously hard to prove statements about Emergent behavior in complex or dynamic systems.
