I'm honestly skeptical that Rust is all that appealing for this type of work. It just doesn't seem like the main concerns like performance and type safety are #1 the top priority in this space and #2 this offering is differentiated enough from what you already get from Java today. Honesly, many modeling problems are clunky and inefficient at scale - however that's ok. When you need to scale bad enough, you already have a significant set of library support in Java to support this. I'm failing to see an answer to the one question I have, "why rust?"
