Space warp!
That became humanity's trump card after they headed into space. This technology was even more valuable than Homo Evolutis because without it, there would be no humanity, much less Homo Evolutis.
Of course, without this technology, Earth wouldn't have been targeted by neutron star fragment and human beings would still be languishing in its warm cradle. In any case, this was an issue of egg first or chicken first, so we shall not get into it now.
In conclusion, space warp was humanity's biggest trump card; it was not be an exaggeration to call it humanity's lifeline. After all, the cosmos was vast, how could a "small" spaceship like the Hope possibly fly in space for tens of thousands of years? When one really thought about it, almost all the level 2 or 3 space civilizations had a mothership that was the size of a small planet. They had to be to reflect the size of the cosmos; how else was a civilization going to last thousands of years in space?
