Generally speaking, the demo is always about finding the green ball on top of a red cube, or the person who went missing in a land slide, but what sells it is detecting and aiming at the dissident hiding under a truck.
And isn't it weird how "think of the children" is always ridiculed but "think of the paralyzed etc." is just fine? I've seen it countless times in the last decades. Just recently when I said on here I want "AI" art to be marked as "AI" made and someone claimed I don't care about the people who have Parkinson's and can't hold a brush, but wouldn't answer why we can't mark it anyway. It's not the people with Parkinson's that want to pass of their creations as hand-made. They're just getting used.
Sure, paralyzed people would love to be able to control a cursor with their mind etc., but even more than that they don't want cuts to social programs, that enable them a dignified life beyond "making them as functional as a healthy person", to allow tax cuts for the super rich. They want friends to have time for them instead of working 3 jobs, that sort of stuff. But Musk and his spiritual brethren are gleefully moving in the opposite direction, as fast and ruthlessly as they can.
So I say this particular doctor is three butchers in a trench coat. I can't prove it, because I can't read minds, but nobody else can either, and this is the "bet" I'm going with. Vulnerable and sick people can only have things that would a.) help super rich people with the same conditions and b.) enable more persecution and exploitation, and an easier discard of undesirable, unproductive or rebellious members of society.
