Will AI replace Molders, Shapers, and Casters, Except Metal and Plastic?
AI can do 1% of the work Molders, Shapers, and Casters, Except Metal and Plastic do at least twice as fast. Real use has not caught up: none of their tasks show up in real AI use yet, but AI could speed up 1 of them. Robots can technically handle 20 physical tasks. 3 still need a person.

Physical tasks that today's robots can perform in at least some settings. Robots are cost competitive for very few tasks so far, so this change moves slower.

Your week is not the average
Describe what you actually do and get a personal report: your own tasks, what AI can already do, what stays yours and a 90 day plan.
What this means
Little of this work suits AI. The bigger change here is robots: today's robots can technically do 90% of the working time, though they are rarely cheap enough to replace people yet.
What to do next
- Get ahead on the 1 task AI could do next. These move as tools improve, so learning them early pays off.
- Keep an eye on the 20 physical tasks robots can technically do. Cost keeps most robots out of work today, so this shift is slower.
- Build on the 3 tasks that stay human. This is where your judgment, skill and relationships matter most.
