I think it's just that many people feel threatened or inadequate when they (naturally) compare themselves to these people. It's tempting to put them down so that we feel better about ourselves. I think most of us here on HN like to think that we're clever but when people like Katie Bouman get under the spotlight suddenly most of us realize that we're not such hot shots after all.
It's probably worse when it's a woman/child/minority/... because it gives us the convenient excuse of "this is probably a PR stunt" to dismiss them. It's lazy and it's intellectually dishonest but it's also very human unfortunately.
This leads to people getting rejected thinking it's part of some culture war, when the truth is that most people get rejected, some of those people would have been brilliant in the role they got rejected for and it's exactly the same brutal industry that it was in the 1980s.
For an example of this that involves a male, the media has been hyping the Ocean Cleanup project because it provides them with a great prodigy story, but people on HN have been rightly pushing back against its merits.
Many people are intelligent enough, but are not going to work hard enough.
She became interested in this problem in high school and stuck with it all the way through. She is a genius, and also the genius who did the work that let this happen.
I think in this particular case, I have no problem with it. One, she obviously had a big part in it. Maybe it is blow back because they feel a picture of the inside of a black hole isn't a big deal and people are making it into something big? In my opinion, it is. I remember middle school teachers almost scoffing at the idea of a picture of a black hole and yet, 25 years later, here we are. Regardless, she in her twenties has generated something that researchers spend a lifetime trying to find so kudos to her. I'm sure there is a certain gendered element to it in both cases (for and against) and it'd probably be naive to think there wasn't.
Even if this were a smaller aspect of what these researchers were aiming for, I'd love to see a documentary series on what various team members worked on (and in her case, discovered). An image generated by radio waves and she (maybe with others?) was able to construct an image out of that? That's impressive. Probably not, but I'd be curious if this kind of thing could be localized in a way that it could be the "sound to visual model" element of a system so that blind people could make out the world a bit more directly (obviously, there'd need to be a means for them to consume said model. All of this is way above me and my pay grade).
