So things like the cotton gin or Ford's use of interchangeable parts don't count as design or somehow didn't change the world?
How is volunteering at soup kitchens more effective at changing the world than interchangeable parts?
And still yet...are you wanting to change the world for the better?
could you frame innovation problems as "design" problems? sure.
was the cotton gin framed as a "design" problem in the sense that it had some sort of epistemological lineage to the "design" discipline when it was invented? I suspect not.
the worst thing design ever did for itself was frame itself as "the" human-centered problem solving discpline. everyone is a human-centered problem-solver in the most general sense, in the same way that everything is a "design" problem in the most general sense.
