It's a bit sad for me. I find the biggest issue for me with pandas is the API, not the speed.
So many foot guns, poorly thought through functions, 10s of keyword arguments instead of good abstractions, 1d and 2d structures being totally different objects (and no higher-order structures). I'd take 50% of the speed for a better API.
I looked at Polars, which looks neat, but seems made for a different purpose (data pipelines rather than building models semi-interactively).
To be clear, this library might be great, it's just a shame for me that there seems no effort to make a Pandas-like thing with better API. Maybe time to roll up my sleeves...
