My experience has been the opposite, with relatives eagerly snatching up the old photographs.
My boss is young and one of those people for whom digital is the only way. Then one day she got a box of old photographs and was absolutely amazed that she could turn them over and read where they were taken, on what occasion, and who was in the photos.
She now prints out all of her photos and writes notes on the back of them and keeps them in a box, just like people have done for the last century.
