Contrary to Richard's comment, I think he is saying there currently is
not the technology to experimentally test the theory. As such, it is
in good company. Most string theory is like that. As to whether the
paper is worth reading, that is a personal taste. So long as it is possible to
test experimentally, or provides a satisfactory explanation (ie
non-instrumental) for existing phenomena that does not have that, it
is not a waste of time.
