Beware, they are different concepts.
Threads offer concurrent execution, async (futures) offer concurrent waiting. Loosely speaking, threads make sense for CPU bound problems, while async makes sense for IO bound problems.

Why? You write the same code with async await but with a keyword at the beginning of every function.
Because if you go down the callstack eventually you won't get the await keyword anymore; you'll get the actual 'waiters' and 'wakers' which define your scheduling
Yeah. The OS handles scheduling and preemption so it’s done for you rather than a call in the stack.
