Modern planes, and other transport/engineering structures, are moving to composites. Which are layered, printed, sometimes pressure baked and squeezed into form. But no longer forged on this scale.
While these machines are awesome, I've wandered along a car body stamping line and watched plates go from a flat sheet to a car door in 100meters, they are becoming less necessary to us. They will still be needed, of course, for some jobs where only such a monster can help, but I think the US should look on these as potential future museum pieces, with nostalgia for a bygone age of megaengineering, rather than a source of future industrial dominance.
