1) the added value in final assembly of components made elsewhere (ie. $10 in components being turned into a $100 final product means $90 in "manufacturing") 2) increases in computing power being value-adjusted in the data as increases in output volume, which is defensible but has grown to dominate the numbers to obscure real losses in manufacturing
I think when people talk about manufacturing, there's some expectation that they are talking about real ability to make things with some degree of self-sufficiency. Saying manufacturing jobs are "lost to automation" seems to disguise that it is largely not the same manufacturing which is being automated.
