Gender is not relevant, unless it is. People need to see folks like themselves represented, and downplaying gender as "not relevant" dismisses the very real effect this can have. Are her achievements awesome because she's a woman? No, of course not -- they're awesome for their own merits. But if one woman sees this and gets inspired by it, that's awesome.
Whether gender is relevant is not a normative question but an empirical question. Given that women were, for centuries, barred from obtaining education and then nudged away from science more than men, it is a very simple empirical fact that gender is relevant. I think it shouldn't be, and hopefully someday it won't be, but it is.
