Claude Skills are going to be the end of all human mental labor, but in a good way.
Eventually, we shall, as a human race working together, also figure out how to generalize this to all AI models, all robotics, and all human skills.
My friend Christopher Santos-Lang wrote a fantastic paper on how every strategy for any given Skill can be benchmarked against every other strategy such that we always end up with the best strategies in our shared universal repository of Skills. See https://arxiv.org/abs/2503.20986
