I think it fits well with your line of thinking. People know it's coming. Imagine sitting there doing nothing about it. An entire species yet. One that is supposed to be intelligent on top of that.
Even the people that don't know how to swim try to stop themselves from drowning.
And I'm confident space will be filled with robotics. Even if something comes along to wipe out humanity and the bots go into standby mode, the next life form to rise above the clouds will discover them. Those chunks of metal will be their dinosaur fossils.
Science-fiction by the way. I think it's an interesting world.
