Programmer and performance expert Casey Muratori explains why reading assembly is essential for optimization:
- Whether you write Java, C, Haskell, OCaml, or Rust, you're only looking at input to a compiler — you have no idea what the CPU is actually being asked to do
- Learning to read assembly isn't hard, and it lets you quickly see whether the CPU is receiving what you intended, information no high-level language provides
Gergely Orosz amplified the take with "Casey is right, again."
