Yes, it seems to have slipped off to the same misty land where
Kaluza-Klein theory, spin lattices and other theories currently not in
favor but not ruled out live.

By the way, I found a text about M-theory, the successor of
superstring theory ("A Layman's Guide to M-Theory" by M.J. Duff,
hep-th/9805177, can be found at the preprint server at lanl). Seems to
be quite fun, and has potential for a lot of truly wild things
(gauge-topology duality, lots of unusual manifolds, "black membranes",
etc) that could one day become playthings for posthumans.
