  Recent theoretical results indicate that the detection of primordial gravity
waves from inflation may be a hopeless task. First, foregrounds from lensing
put a strict lower limit on the detectability of the B-mode polarization signal
in the Cosmic Microwave Background, the ``smoking gun'' for tensor (gravity
wave) fluctuations. Meanwhile, widely accepted theoretical arguments indicate
that the amplitude of gravity waves produced in inflation will be below this
limit. I argue that failure is not inevitable, and that the effort to detect
the primordial signal in the B-mode, whether it succeeds or fails, will yield
crucial information about the nature of inflation.
