I love this paradox! It actually transforms into an interesting general heuristic for life[1]: basically, any time reality throws a categorization boundary at you (you observe f(a) = X and f(b) = not-X), gradually transform it (a to b) until you see exactly where the category flips.<p>For example, if you have a bug in case A but not case B, gradually transform A into B and see where it disappears.<p>If a law says that you can do X in condition A but not condition B, see if it&#x27;s legal midway between A and B.<p>[1] which I call the &quot;continuity heuristic&quot; since it depends on reality obeying a rule that if a is close to b, f(a) is close to f(b).
