Sure, and I can't figure out whether the guy who is letting me in to traffic instead of cutting me off is malign or benign, because I lack a definition of those words. Alas, I am doomed to infinite confusion forever.

It's very fashionable to confuse the inability to draw bright shining lines as being unable to define a thing at all, but I don't have much respect for that attitude. Of all the outcomes, "the probe engages in indefinite behavior that we are never able to classify as 'humanly benign' or 'humanly malign'" is such a low percentage that it's something I'll worry about when it happens.

The world is full of concepts we can't draw bright shining lines through. In fact the ones we can are the exceptions. We manage to have definitions even so.

The probe comes in, observes half a dozen major armed conflict areas on our planet, and solves the problem by entirely disintegrating all weapons on one side of each conflict with no loss of life (but leaving the other side's weapons untouched).

1. Would your assessment of "malign vs benign" depend on knowing which side was disarmed for each conflict, or can you already make an assessment without that information?

2. Do you estimate that the other 8 billion humans surely agree with your response to #1?
