> Paper will last, a 100 or so years

afaik even the best color papers (for wet prints) will last 20-50 years before starting to show color shift, that's in a darkbox with optimal humidity. b&w obviously is much better

Modern pigment prints seem to perform a bit better, 65-120 years according to some studies
