It was and perhaps still is, a solid competitor to Photoshop, but any unfamiliar grownup is, quite reasonably, going to never ever ever trust anything to do serious work with a name like that.
It really conveyed the image of cheap and shoddy. The drab looking logos, the name, and the weird looking poodle: all that just made it harder to take serious.
Players of magic the gathering will say a creature "has flying" by which they mean "it can only be blocked by other creatures with reach or flying".
Newcomers obviously need to learn this jargon, but once they do, communication is greatly facilitated by not having to spell out the definition.
Just like games, the definitions in mathematics are ethereal and purely formal as well, and it would be a pain to spell them out on every occasion. It stems more from efficient communication needs then from gatekeeping.
You expect the players of the game to learn the rules before they play.
I'd say the ability to take complicated definitions and to not have to through a rigorous definition every time the ideas are referenced are, in a sense a form of abstraction, and a necessary requirement to be able to do advanced Math in the first place.
People increasingly seem to forgo the idea of retaining the data for themselves because they find AI products so fascinating / useful that they're just not caring, at least for the moment. I think this might swing back in the favor of Apple at one point, but right now it is kind of fascinating how liberally people throw everything at hosted AI models.
I personally don't use them. So I just get to observe.
(The reason I did that is that the anti-crawler protections also unfortunately hit some legit users, and we don't want to block legit users. However, it seems that I turned the knobs down too far.)
In this case, though, we had a secondary failure: PagerDuty woke me up at 5:24am, I checked HN and it seemed fine, so I told PagerDuty the problem was resolved. But the problem wasn't resolved - at that point I was just sleeping through it.
I'll add more as we find out more, but it probably won't be till later this afternoon PST.
