When I evaluate a technology for its appropriateness I first look at who's using it: Literally "Who are these people and what are they working on with this stuff?" The answer to this question determines more than 80% of the decision on whether the thing is going to be my choice.
Rust seems to be being used most by people who are interested in blockchain and crypto. They tend to be of a near monolithic ideological caste, too, which has its own problems. Do I want to get into a situation where I might have my hat in my hand with these folks? Not really.
(also the rust compiler is so slow I cannot believe it)
