If you can build your own processor fab today for €100 000, you are definitely exploiting economies of scale. It is possible because of the massive existing industry that's created the market for, and driven down the price of parts and tools and supplies that you need to put it together and run it. E.g., that inexpensive off the shelf laser cutter you need to buy.

But that's not “how prices drop as you make more of something is the "learning curve"”.

OK, I see where we are misunderstanding each other. I was was trying to say that the decreased cost as you make more of something comes from economies of scale more than the learning curve.
