In any social media facilitated discussion about programming the topic of code optimisation with often arise. Anyone who has expertise in low level optimisation are likely to face a choice: being silent or enduring endless accusations of irrelevance and hubris. Most choose the former approach as a more efficient and effective path to take, even if they earn a living developing and maintaining optimising code generators.
The idea that Compilers Optimise Code Better Than Humans is, I argue, another Moth of Programming: an idea that has become popular in software engineering due to virality instead of reality.
