I don’t think it’s so black and white. Depends on what you’re doing. If you’re doing lots of cross dataset operations like econometric and physical system modeling polars can get a bit too verbose. Eg how would you do the following two pandas operations in polars?

    capacity_df - outage_df

    prices.loc['2023-01'] *= 1

There’s many workflows and models that do thousands of these types of operations.
