Rust

Python's accessibility flooded the market with junior developers, creating intense competition for entry-level roles. Companies migrate to Go or Kotlin for performance/type safety, and AI startups prefer Julia/Rust, leaving Python devs maintaining legacy models.

Mojo offers Python interoperability with C-level speed; Julia dominates scientific computing; Rust leads systems programming; Zig and WebAssembly-centric languages dominate edge/IoT. Python loses use-case ownership across domains.
