Tippi Benjamine Okanti Degré, daughter of French wildlife photographers Alain Degré and Sylvie Robert, was born in Namibia. During her childhood she befriended many wild animals, including a 28-year old elephant called Abu and a leopard nicknamed J&B. She was embraced by the Bushmen and the Himba tribespeople of the Kalahari, who taught her how to survive on roots and berries, as well as how to speak their language.
I think that a lot of the reason Jarvis has become so human is because Tony treats him like he’s human. Tony talks to Jarvis in a very colloquial way. He says “you up?” when he knows damn well that Jarvis is operational. He says “throw a little hot-rod red in there” instead of “paint components x, y, and z with red paint #20.” Tony treats all his machinery like that—Dummy and You, especially—and Jarvis is no exception.
Jarvis has become much more human since Iron Man 1. He actually displayed emotions in Iron Man 3—specifically when he feared for Tony’s life, his voice sounded terribly frightened, and in instances like the second gif where he said “I need to sleep” and not “My battery is depleted.” Jarvis has grown and changed, as any self-aware creature does. He has become human because he is treated as such.
