"Theoretical ML papers do not tell researchers the identity-covariance gaussians exist. Researchers already know that identity-covariance gaussians exist. Theoretical ML papers tell researchers the identity-covariance gaussians can be killed."

(G.K. Chesterton, on spherical high-dimensional dragons)

I really want to understand this quote! Is Chesterton's use of "killed" intended to mean "can be avoided in practice, leading to many upsides?"
