Both are different ways of illustrating the same, IMO. For xSE, only direct developments matter - for an effect to be considered, it must be clearly visible and its consequences known. Approximating unknown aspects is in opposition to this, and I've yet to see xSE do so, much less effectively. I compare Si to weak and Ni to strong emergence - the former claims all effects of interactions are accounted for, while in case of the latter, the whole point is they aren't directly (explicitly) traceable to the properties of the system - each focusing on the aspects the other ignores.
And it really needn't be time-related - development over time is merely an example of information better suited to Ni, simply because of the unaccountability of all the factors.
