Robots are typically seen as having no consciousness. But potentially they have the highest kind: equanimity. This is the emotion Buddhism counts as among the most sublime.

Going about her daily rounds, she’s something like blithe—both self-contained and indifferent to human value systems. As for abundant, exalted, and immeasurable, I can’t be sure. How to measure these things, or is that what “immeasurable” means?
