TLDR: Instead of an assembly line where items are constructed piece by piece, robotics could work together ["swarm robots"] simultaneously to build the product in one go, faster and and better. AI will make this much more practical. There may be truth to the above, but it's not binary. No doubt AI is already being used to speed up some production line, somewhere - and as AI improves, each machine may be able to do more. But having 100 hands working together doesn't necessarily mean you have a better final product.
