I think you're flirting with induction here. A child does not learn to be intelligent, especially not via instruction from without. He is born intelligent. What knowledge he creates using that intelligence and whether IO may help with that are different matters.

"How can we build beneficial AGI?" is yet another "Who should rule?" question. It should be replaced with "How can we detect our errors in building AGI?" and then, once built, "How can we help AGI learn?"
