An example of an important human task that is not "economically valuable" in this sense, is caregiving within a family, such as parenting, since parents are not employed in that role. OpenAI is not setting the goal post that far, to say that they are aiming to develop a machine that is superior to humans at all tasks, including such tasks as raising a human child. That would be ridiculous. Focusing on "economically valuable" tasks (the jobs that humans are employed and paid to do) sets the goal post more realistically.
