Ada
In plain terms
A highly reliable language for safety-critical systems.
Going deeper
Ada was designed for systems where failure is catastrophic, with strong typing, concurrency, and rigorous checks. It's used in aerospace, defense, and rail.
Under the hood
Strict compile-time and runtime checks plus the SPARK subset enable formal verification; reliability is prioritized over convenience.
Examples
Avionics, rail signaling, defense systems, the Boeing 777, satellites.
Think of it like...
Like an aircraft built with triple-checked engineering: heavy on safety because lives depend on it.
