Stephen Wolfram Has Figured Out How to Talk To Aliens

In January, Stephen Wolfram — the computer-scientist, part-time epistemologist, and author of both “A New Kind of Science” and the Wolfram Language, a “universal” programming language that (among other things) informed the alien communication in the movie Arrival — wrote an exceedingly long blog post about how best to communicate with aliens. It was called “Showing Off to the Universe: Beacons for the Afterlife of Our Civilization.” In March, Tim Urban of waitbutwhy.com called him up to talk about it.
