they came for the speed but stayed for the API

This is exactly how I would describe my experience. When I talk to others about polars now I usually quickly mention its fast up front, but then mostly talk about the API, its composability, small surface area, etc. are really what make it great to work with. Having these same semantics backed by eager execution, query optimized lazy API, streaming engine, GPU engine, and now distributed auto-magical ephemeral boxes in the sky engine just make it that much better of a tool.

Being both eager and lazy does make it sound magical.
