Do you have any citation on why "Dask doesn't consider their distributed version" to be ready? If it is your own view, then that's ok.
I think dask is in heavy usage in real production systems. Let me cite one such usage here, from Capital One (no affiliation, just referencing a big bank for 'production ready' purposes) https://www.capitalone.com/tech/machine-learning/dask-and-ra... (also not necessarily suggesting any rapids/GPU usage, you can decouple it from the article)
And note the article is from Nov 2019. Two years is a substantial amount of time for further improvements.
