Threading models have evolved from single-threaded architectures to complex multi-threaded and parallel execution paradigms.
Single-threaded systems are still relevant due to simplicity, maintainability, event-driven efficiency, reduced context switching overhead, scalability with distributed systems, and security.
The future of threading models involves hybrid approaches, combining single-threaded event loops and worker threads or process-based concurrency.
Understanding when to use single-threaded vs. multi-threaded approaches is crucial for designing efficient software.
