Related: Peter Jackson's They Shall Not Grow Old [0] is a great counterpoint to the general idea put forth here. If you've not seen it, do yourself and ANZAC Day treat and watch it this evening. It's from just before all this AI stuff went off. Jackson (of LoTR fame) is a huge WWI buff and was approached by the Imperial War Museum and the BBC for this film.

One thing that surprised me was that they did the transition from original to enhanced footage so abruptly; I'd expected a smooth transition over a couple of minutes where you don't even realize it happened until after the fact. The abrupt transition didn't get a crowd reaction when I saw it, but maybe that collective gasp was the goal and it just didn't work out in this showing.
