As one of the resident relativity weenies on the list, I'd have to say
that the physical difficulties of superluminal travel are not likely to
be overcome by 2050, if ever, even if huge amounts of energy are
available. The only remotely plausible superluminal loopholes are in
some rather esoteric consequences of general relativity that are truly
difficult to create (when they are not, on further analysis, impossible
to realize in a finite universe). I think we're going to have to settle
for subluminal travel, which still at least allows us to get to distant
stars in a human lifetime.
