https://types.pl/@graydon/111144025966056604 makes me wonder, what other engineering truisms are overrated?

A related one that I often heard in contexts where it was wildly wrong was "engineer time is more expensive than CPU time", e.g., I would sometimes hear this from staff engineers at Twitter, but if you just looked at hardware TCO compared to eng compensation, they were roughly comparable and, at the margin, you could probably cut costs by 90% (WAG) if you seriously spent 10% of eng time on cost cutting.
