Rust won't save your firmware. Your architecture will.
Memory safety matters. But most embedded failures aren't buffer overflows or use-after-free. They're state machines that deadlock, interrupts that block each other, watchdogs that fire, timing violations that surface only at -40°C, and silicon errata that vendor documentation pretends don't exist.
Rust fixes one class of bugs. It doesn't make your ISR timing deterministic. It doesn't prevent priority inversion when two tasks fight for a mutex. It doesn't stop DMA buffers from aliasing when cache coherency is configured wrong. It doesn't eliminate race conditions in shared peripheral state.
The teams shipping reliable product in safety-critical domains know this. They choose architecture first layers, scheduling strategy, resource ownership boundaries, then implement in whatever language fits the constraints. Architecture beats toolchain every time.
What's the most overhyped tool you've seen teams adopt without fixing the underlying design?
