Trying not to be totally contrarian :) so with following expressions I am not a smart ass, only setting up sentences in such way to convey what I think is hard problem in delivering software. But good luck if you have 5 X(lang) developers to make that decision to go with Rust. If you have to deliver v1 of a product and have limited budget, good luck hiring 5 brand new Rust developers. What I learned as boy scout - first you have to have people that want to do the work - having loads of money can help but most of the time we don't have unlimited supply of money. Having people who want to do the job beats everything. People that are deep in tech X(or lang) rarely switch to something else and then you still have to take into account that they will write X in Rust which might not be the best way of doing things. On the other hand if we assume spherical cows or unlimited budgets/unlimited time frames for a project - we can discuss getting X devs to write in Y language.
