Earlier quoted context omitted.
Because obviously someone's title declares what he is capable of or likes doing. Because someone with a title that isn't 'hacker' instantly discredits his ability to hack. Obviously. Because people who didn't study CS can't be hackers, obviously. Because someone who does UI or UX can't hack backend things, obviously.
Yes, and because we all know that no computer scientist has ever done anything unethical, obviously.
But I'm going to put this out there and say your are misinterpreting his comment.
There is a whole lot of "rockstar" talk when it comes to software now; "amazing" engineers or designers that will change your world(TM). It would seem that revolutionaries and visionaries are a dime a dozen now. However, more often then _I_(and I'd argue the parent as well) would like, the whole thing turns out to be nothing more than smoke and mirrors. That type of behaviour bring the whole community down. Its not that UX designers or agile engineers or whatever are bad, they are clearly some of the most valuable and hardest working members of the technical community. Its just that when I see a piece on the next great mind in software, I get this knee-jerk reaction to think "hypppppppe."
Which is what I thought when I clicked the link. But this article plays counterpoint to that world. Here you got a guy, unkept, on his way to being a computer scientist, probably never meet a VC in his life, who is also a hacker. And instead of talk, he is putting forward some rather boring, technically difficult to implement, but useful, stuff. What's more, he is not trying to be like, "I'm better than this company," instead he's got a real grasp on the scale, penetration, and limitations of his work. Its just refreshing.
Perhaps the parent could have worded things better, but I'm not sure he intended to be insulting.
