Apple's GoFetch silicon security fail was down to an obsession with speed

This opinion/analysis piece describes 'GoFetch,' a hardware-level side-channel vulnerability in Apple Silicon (and reportedly similar issues in Intel 13th Gen CPUs) where a Data Memory Prefetcher (DMP) can observe/cache pointer patterns and leak cryptographic information. The article explains how the design trade-off between speed (prefetching and caching) and secrecy (constant-time cryptography) enables the flaw, criticizes the secrecy around chip internals that delays discovery, and calls for greater transparency to improve security.
