Personally I think the innovation required to refine something pales in comparison to first inventing something new. It’s just so less risky and so less expensive. You start with something that already know works and that’s huge.

If you’ve ever tried to DIY something, it’s so so much harder if you can’t find someone who has done it already.

So to me, the people who may have made 3D printing cheaper aren’t exactly in the same class of innovation and risk.
