I can explain why. Java is great for web, api's and most things. But Java is not really that great for doing data science. Python is great for data science, the Python community has put a great effort making Python "The place to be for Data Science" and Rust helps us speed up heavy tasks that are too slow with Python. It is not really crazy complicated, it's simple stuff that is very well documented. We try choose the right tool for the job, and we don't care about which language we use. If we tried to do everything in Java, we would spent at least 2x more time on building our software.
