This NYT article, “Is the Universe a Simulation?”, discusses the argument that it is statistically probable that we’re all living in a computer simulation, and that what we call mathematics is just us deducing some of the code that runs the simulation.

In some ways this strikes me as pure semantics, but it’s also pretty fascinating to contemplate.

“It seems spooky to suggest that mathematical entities actually exist in and of themselves,” Edward Frankel writes. “But if math is only a product of the human imagination, how do we all end up agreeing on exactly the *same* math?”
