Not to me it doesnt. To me, it simply says either they havent found this
area interesting to explore, or (more likely) its too far to travel.
Even if ET can travel at faster than light, it will take a very very long
time to explore even a small part of the galaxy.

Galaxy is 100,000 light years in diameter. Age of universe is
13,730,000,000 years. Aliens who could travel at the speed of
light could zip back and forth across the galaxy some 68,650
times in that time.

So: the galaxy is pretty small, cosmically speaking - and so the
original interpretation of the Fermi paradox is probably not far
off: if there are intelligent aliens in our galaxy, odds are
they are would be everywhere - so probably there are no aliens
in our galaxy - and SETI is mostly barking up the wrong tree.
