When my kids watch the movie "Big Hero 6" I'm sure that the coolest things Baymax does include flying, shooting his fist like a rocket, and doing karate. However, I'm impressed by the plethora of healthcare functions he performs. Not only does he diagnose and treat healthcare problems, but he does so without external aid.
When spraying Hiro's arm with bacitracin, he does so using his finger. This suggests that he either has a container of bacitracin within him, or a means of chemically producing any substance. Either way, this is impressive. As bacitracin is not the only antibiotic that might be used, if he has a container of it, he probably has a container of every known drug. If he internally produces the chemical, then the technology within him is unprecedented. A mobile, human(-ish) sized machine that can create any chemical? Bank.
Equally impressive is his scanning function, which, at one point in the movie, identifies Hiro's peanut allergy. It's already impressive enough that it's able to determine a person's blood levels of neurotransmitters and their blood type. To do so would require identifying molecules inside the person, which is unfathomably impressive. But to identify a peanut allergy is a billion times more impressive. He would have to run peanut allergy simulations on every immunological binding protein in the body, of which there are innumerable. Based on the scanned structure of every molecule in his body, Baymax would have to recognize the potential for peanut molecules to bind and activate the immune system. With neurotransmitters, you could estimate a quantity based on an approximate density in a particular area or something. But to recognize a peanut allergy would require a lot more precision, or you might miss it. And it could be life-threatening to diagnose someone as having no allergy when they actually have one.
So, I guess science fiction is cool to kids and grown-ups alike. No news there. :)
