Ask HN: Who is a Superhero backed by an engineering marvel?

I re-watched an old Ironman movie recently, this made me think, Jan-2023, how far are we from people wondering around cities with superhero powers backed by some engineering ingenuity? A super strong robotic arm ? Gun that hits a target by touching some screen and hitting OK? .. or is it already here and I just missed the memo ??

Pretty much everyone in a developed country. Just zoom out your time perspective. I'll go ahead and say paramedics, but there are examples all over the place.
