"I do not want to care if everything my processor performs is async." The point is not the processor. The point is that all IO operations take time. Processing the IO operations concurrently with the serial program logic is where the beef is. Writing asynchoronous code in C or C++ is tedious to say the least in my experience, with weird concurrency bugs looming everywhere.
