[cryptography] Well, that's depressing. Now what?

This has been covered to death by now, both today and in the past
(search the archives of this and similar lists).
Until we see scalable quantum authenticated quantum secrecy / key
distribution, QKD is not suitable for production deployment. This is
the position that most of us here hold, and it is not religious. It
is utterly simple to understand why we hold this position. This isn't
like, say, catastrophic anthropogenic global warming theories where
the system of interest (Earth's climate system) is incredibly complex
with many known unknowns and who knows what unknown unknowns, but
relatively simple engineering problems (trivial by comparison to the
first). Many smart (but not necessarily brilliant) people can
acquaint themselves with the technologies involved here in reasonably
short order and decide for themselves if QKD is a truly useful
technology or not.
The field of applied quantum mechanics is certainly not snake oil, but
QKD as a product sure is.
