I agree with highly technical and ongoing. I'm agnostic about "very expensive." Initially very expensive, sure. But how much of the expensive stuff can be eventually automated and routinized? I'd guess "a lot," since that's my general guess about the future, and in that case the cost would fall a lot as well. If I'm wrong -- and I could be wrong; many predictions of widespread automation have been premature -- then I agree that the costs could remain very high.
