The same group (Nvidia/Rapids) is working on a similar project but with Polars API compatibility instead of Pandas. It seems to be quite far from completion, though.
I've been watching cuda since it's introduction and Polars since I had an intern porting our Pandas code there a couple years ago but I had no idea Polars would go this far, this fast!
