 In their bare essentials, the two types of indeterminacy are the same (and it is possible to construct cases of intermediate types). In each case, we are not sure how to pin down the career of an object. In fuzzy-boundary cases, we don’t know which of many overlapping career paths an object follows (one which begins earlier, or later?); in radical disruption cases, we don’t know which of (at least) two intersecting career paths an object follows.
