A better measure would be how much work has been made unnecessary.
The asymptote approached by software engineering is GDP=$0 because all problems are solved by maximally efficient automation. Never gonna happen, but progress on that path is a decent proxy for efficiency.
Too often the job is about introducing problems that are good for some company's bottom line, but that's the opposite of efficiency.
