Arrogant is a tremendous understatement. There's a chance that 10 million years ago on some other planet existed a far more advanced civilization than humans could ever imagine, but they died out after 1 million years. So they would have had 1 million years of advancement, which is still 50 times more advancement than the 2000 or so years of scientific progress we've had, and even that would be but a tiny tiny tiny fraction of a blink of an eye in space and time. To think that "humans have a viable chance of surviving cosmic time" is incredulous if you know even rudimentary physics.
