Why is everyone out of chassis springs?

Re: replacement bodywork: I have seen new technology that utilizes computer-controlled power hammer on a robotic arm (more like a frame) to form sheet metal into complex curves. The demonstrations online have shown fairly small pieces, say 12” in diameter, but I presume this technology will continue to advance. I won’t be holding my breath for the day it can work Model A gauge steel for fenders, and I won’t predict what the cost of production will be. I hope I see it and can afford it in my lifetime.
