With the advent of FBW, and computers that can automatically adjust control surfaces many times per second, inherently unstable aircraft have become feasible - e.g. the B-2.
It depends how the wing is designed. The Horten gliders in the 30ies (flying wings as well) were actually stable from the reports of those that were lucky enough to have flown them, especially the HO IV.
