Raw <code>std::thread</code> and manual mutex management lead to deadlocks, race conditions, and suboptimal CPU utilization. Modern task parallelism libraries abstract thread management behind high-level APIs — you describe <em>what</em> work needs to be done and <em>which tasks depend on each other</em>, while the runtime handles thread pools, work stealing, and load balancing automatically.</p>
