It doesn't. As a freelancer if I type "rust" on upwork right now I get only 26 jobs. If I type "golang" it yelds 104 jobs. But if I type "php" I get 7966 jobs; "java" = 2547 jobs; C# = 1174 jobs. Even "Assembler" gives 292 results, more then double of both rust + golang combined. For me Rust / Golang / Swift are those Instagram "influencers" that the press talk a lot about it but have little power in the harsh reality of the world.
