Why Are There So Many Databases?

Snowflake might not be the cool kid forever, especially as BigQuery and Redshift learn a few tricks. DuckDB can handle small tasks at home, but toss it big data and watch it sweat. Data Lakes whisper about saving cash but then slap you with setup headaches. PostgreSQL is the MVP, effortlessly outdoing MySQL in most scenarios, while SQLite quietly dominates the embedded world. Those "hip" Document databases like MongoDB might just be a passing fad, and Graph databases are like a Swiss army knife that only solves that one puzzling problem. Vector databases are having a moment thanks to the AI frenzy, but multi-model databases like FaunaDB tend to promise the moon and deliver a pebble.
