DARPA did kinda try and automate sewing - https://www.wired.com/2012/06/darpa-sweatshop/ Uniforms are billions of dollars.

I think what's important is not they bought 3 toilet seats for $10,000 on planes that costs $100,000 a hour to fly.

Universal Camouflage Pattern costing $5 billion to develop and make, then gets ditched because it sucked feels like a bigger story. How does that happen.... Isn't that the military's main interface with the world.
