Some will probably exist as exhibition pieces in places like Williamsburg, but a lot of the practical skill and techniques are in danger of being lost due to lack of use. Among the skills that I would like to see preserved are things like flint knapping, blacksmithing (blade smithing is still doing fairly well), foraging, manual land navigation, and to an extent manual stone carving / banking masonry.

Much of the manual nature of these skills has been replaced by automation or handheld electronics, so they are practiced by a dwindling number of artisans.
