It is interesting that your speculation chose this path: Java to Rust. That surprises me! I would have much more likely to say, C, C++, or Go to Rust. Was your choice of Java arbitrary, or is there a deeper reason?

A bit late response, but I think I just picked Java as a generic corpo language.

imho web shops looking for the new shiny have tried to use Rust in search of more type-safety or performance (or to look cool)

Companies using C, C++ or even Go probably are less keen on switching stacks for the sake of it.
