> your code is not fast, efficient, reliable, convenient or secure because you say so. I often would be in meetings where tech folks would introduce their code (to non-technical audiences sometimes) as 'tight' or 'super fast' or... similar. It was cringey every time, and... often wrong. Yay - you got a query down from 8 seconds to 2 seconds. That's not really 'super fast' though - with a bit more work (or experience) that would be 300ms or less (which I eventually did with about 30 more min of rewrite and indexes).
