Datomic is, as far as I'm aware, a general purpose database. What it isn't designed to be is a familiar database.
SQL is what people are familiar with, and even some NoSQL databases have distinctly SQL-inspired query languages (e.g. SimpleDB). The problem is that SQL is a godawful query language, and if we want to do better we need to do something different, and therefore unfamiliar.
SQL tries to look like natural language, which has resulted in a syntax is complex, inconsistent and monolithic, just like the language it tries to imitate. If we want a syntax that is simple, consistent and modular we need to throw away the idea that a query needs to read like English.
