OP is talking about being surprised by steady progress to a major human achievement, one that could save a million lives for starters, but also one that in its mature state (where robots can visually interpret and navigate 3d space) unlocks even more labor saving automation than cars, busses, and trains put together. It has the dark side of military uses, sure, but given how developed our tools for blind destruction already are, robots that can see the world will make a much bigger dent on the positive side. Progress on this is genuinely exciting and people should let themselves feel that even if they don't like Elon Musk.
