That's not really what's being said. We know there's more to find; we know there's problems with our current understanding; we know we haven't found "the bottom".
The problem is, we've found what looks like a bottom, and all the looking we do for cracks in it, or knocking on it to find hollow spots, or hitting it really hard to try and bust through, just keeps coming back with everything being unbroken, solid, and unyielding.

It's not self-congratulation; it's frustration.
