That was probably just the writers trying to use an inverted trope:

What's inverted about "bumbling idiot male hacker"?

>a trope that typically applies to males is applied to a female character, or the other way around (Gender-Inverted Trope)

If the trope is "basement dwelling male nerd = good hacker" then they're inverting it and making the female a good hacker.

They're both excellent hackers. In addition, she is cool, whereas he is a bumbling idiot responsible for comic relief.

You're missing the point, "cool female hacker" isn't a trope.

The original comment suggests that it quite definitely is a trope.

(Which is fine, of course. But let's not kid ourselves that we're breaking media stereotypes that were gone years ago.)
