Why is Kotlin Flow considered safer than RxJava in structured systems?

Flow integrates with structured concurrency, preventing lifecycle leaks.

RxJava is powerful but unbounded by lifecycle unless manually managed. Kotlin Flow is built on coroutines, meaning it automatically participates in structured concurrency. This ensures cancellation propagation, preventing memory leaks and orphan streams. Flow is also cold by default, making execution predictable and reducing unintended side effects.
