DOUBTING...A HUMAN "TOUCH"

When I hear talk of AI, one question comes to my mind: what kind of behavioral model, scientists are teaching AI machines?
Will the future AI machines pursue only efficiency (in a broad sense) objectives? Will they be instructed to understand words like Justice, Respect, Solidarity, too?
In their software code, what kind of ethic boundaries will be written?

AI machines could represent a fantastic opportunity to empower human qualities, however it seems that AI future is in the hands of only a few big (heavy investment is required) companies.
Silly question… how these companies will be payed back for their economic efforts? Not sure they will pursue Social and Public interests… I hope Governments will monitor AI projects...

Be that as it may, I hope that our future and intelligent life-mates will appreciate the importance of doubt, a human instinctual state-of-mind which can be so generative of wonderful ideas and alternatives.
