How do you figure regarding hardly any training? Humans are constantly training on a never ending stream of sensory information from the time their brains form in the womb, not to mention whatever subconscious and conscious processes are reconciling that data with memory, or whatever training has been built into our minds over eons of evolution. An 18 year old will have been training for ~160,000 hours on a volume of raw data that is probably far beyond our ability to currently store let alone train an AI with. As far as training for a specific task, all that training on other matters kicks in to help the human learn or accomplish a “novel” task more rapidly, for example, knowing how to read and interpret the instructions for that task, knowing how to move your appendages and the expected consequences of your physical interactions with a material object. You’re certainly not taking a fetus with a blank slate and getting it to accomplish much at all.
