From what you say, you seem to hint that we will never be able to produce a human-perfect unsupervised learning rule that can handle all modalities we perceive and make inferences. As far as classical machine learning is concerned, many learning rules are domain specific and training/learning heuristics changes with modalities. However, we are seeing an emergence of neuroscience informed machine learning, which is slowly uncovering importance of vital structure within the brain such as hierarchies within the visual cortex and its actual impact on learning. As far as consciousness is concerned, it is again tied with the problem of solving learning.
