Well, it’s true you have to train AI like a child, I think there are some things worth noting though.
A human has to be raised because it’s only born with genetic memory, such as drink milk, cry when hungry, all that stuff. It has no inherent understanding of society, languages, survival, or scientific knowledge.
Basically humans are a package you can drop anywhere and it will (hopefully) learn how to adapt to its surroundings.
I think robots can be a bit more robust than that. Its “genetic” memory can include encyclopedias of knowledge, translators of every language, scientific and mathematical calculators. Basically all that’s left to learn is how to adapt to its surroundings and its local society.
If you don’t want your robot roaming around town learning how people interact with each other, you’re gonna need to program in a personalty. At the very least its going to have to learn to live with you, hopefully it will enjoy that.
