Rust as a career choice: Am I being unrealistic by focusing on it?

I’ve been learning Rust as a hobby, and I love the language—its design, performance, and safety features really click with me. But I’m torn about whether it’s realistic to aim for a career focused on Rust, or if I’d be better off investing more time in mainstream languages like Java/JavaScript for job security.

• For Rust developers: Are you working with Rust full-time, or is it more of a complementary skill in your job? How hard was it to find opportunities?
• Is Rust’s adoption growing fast enough to justify specializing in it now? Or is it still mostly limited to niches (e.g., blockchain, embedded, systems tooling)?
• Should I treat Rust as a long-term bet (while relying on Java/JS for employability) or is there already a viable path to working with it professionally?

I’d love honest takes—especially from people who’ve navigated this themselves. Thanks!
