I'm one of the original Luigi authors, and used to maintain it for a while, merging PR's daily etc. I left Spotify a couple of years ago. Since then it's been maintained mostly by Arash Rouhani, who is increasingly getting busy with other things.

But it's very much in active development and there are multiple pull requests merged every day.

I haven't had a lot of time to check out Airflow, but it seems great. Data engineering and thinking of data processing as functional pipelines is a great paradigm, think we're going to see a lot of future development in this area. Luigi will probably evolve a lot over the next few years. Eventually I think there will be better frameworks. No idea if Airflow is a step change, I think there are still projects yet to be built that unifies everything beautifully
