It's like watching a ballerina dance. It's like seeing an invisible hold never let go. It's a multi-axis laser cutter with such pinpoint accuracy that it never moves from the spot it's set at. It's impossible. If these are our future robot overlords, it makes complete sense. Take me now.
Machines are great at doing repetitive tasks, scales above a human. Save for one thing, most manufacturing machines can't think on their feet. If the part is slightly out of alignment, or just plain wrong most machines won't catch it and that can do major damage. Regardless of a machines ability to do the task, it will always require a human operator, maintenance and inspection. It's not that we lose the skills, our skillset merely changes.
