While my words may be failing, friends continue to eloquently express their sadness. I love nearly everything Matt writes, and his tribute to Aaron Swartz is beautiful.
The mathematic or computational prodigy is legible, domesticable; Aaron was far stranger than this. Ungovernable, irreducibly feral, his genius took utopia as its object. In a now-irretrievable alternate future, vastly more people use code to share, to learn, and to grow together. And Aaron Swartz is alive.
