That might be true for hobbyists or side projects, but employees definitely won't get to work less (or earn more). All the financial value of increased productiveness goes to the companies. That's the nature of capitalism.
I don't think it's meant to be literal, more tongue-in-cheek. Obviously, developers aren't going to be playing table tennis while they wait for their task to finish. Since it's async, you can do other things. For most developers, that's just going to mean another task.
