In short: "Structured concurrency organizes concurrent tasks as 
tree-like hierarchies. This means that any child task is 
logically nested within its parent. When a parent task finishes, 
it waits for all its child tasks to complete or is automatically 
cancelled if the parent task fails."

This tree-like hierarchy achieves 2 important things:

- It improves reasoning of the code, like structured programming 
did;
- It ensures lifetimes of concurrent tasks follow the same 
structure, instead of the fire-and-forget approach.
