It's kind of the-chicken-and-the-egg scenario. I wanted a hospitable development environment to build a hospitable development environment. Also, prebuilt binaries work just fine. I made this in around eleven hours, so it should be fairly easy to rewrite in other languages if that is what the community wants. This project is already getting a lot more attention than I was expecting, and it is definitely still in alpha. However, you can use whatever tools you want to use.
A good goal for these sorts of projects is bootstrapping - can you build seastar with seastar?
