Have we failed as a species?

[Aoi Magi]

You missed the point, I said "As long as we survive" we have succeeded, so if a freak meteor destroys us tomorrow or we nuke ourselves to oblivion, we certainly would have failed but till before that point, we would still be a success story.

That's like saying we are all geniuses until we score 3 on the IQ test.

First, The IQ test isn't actually a good measure of intelligence.
Secondly yes, genius would be a comparative degree of intelligence in the IQ test but even someone getting a low score doesn't mean they are not genius. A genius painter, or artist does not need the intelligence of a rocket scientist.
Third, you are still missing the point. Instead of putting humanity on a pedestal, look at it as just another species and then look at all other species, nature is constantly cleaning up the failed species and the survivors are doing their best to adapt so as to not get wiped out by natural selection next,
