Agree, I don't buy the notion that mathematics is a craft, it's a pursuit of knowledge. A better analogy might be cartography where people spent a lot of effort mapping unknown regions and now we can take pictures from space. This is both faster and probably more accurate and there are basically no unknown regions left so there's less motivation to do it anymore.

That said, there's nothing stopping anybody from mapping out an area today if they get a kick out of it. The gripe with mathematics is less about the loss of a craft and more about a superior solution replacing the old approach as the best option; the old approach very much still exists though.
