"Refined motor skills are like "autopilot." Even in light of fatigue, you'll know how to correct your form. "
"So if motor skills are like natural language, then maybe we can apply things we know about the latter to the former. "Natural" motor skills: their fluidity, robustness to perturbation, and extremely precise yet very compliant control, are hard for robots perhaps the same way language is hard for computers."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
