I’m not necessarily convinced despite my human bias that it’s a superior mechanism. Humans work the way they do and learn the way they do in no small part because of biological limitations and a physical reality. It’s not clear that a virtual entity needs to face the same limitations, although clearly learning from feedback that’s not available to an AI is important. It is true though that humans are more energy efficient learners, but letting the AI experiment with the real world and get feedback that’s way may be the only missing piece rather than a problem with the “blender” approach.
