So stupid to worry about things that far out in the future.
Look at how America has transformed technology in a 240 years.
If we are still around in even a few thousand years, this will be a minor issue. By then, we’ll have cracked interstellar travel (sub-light or superluminal speeds), colonized a huge chunk of the solar system, and be able to use technology to survive just about anywhere and in any environment.
Just silliness.
Oh yeah, and the way things look, HE might be coming back a LOT sooner than that. Then all these things REALLY don’t matter.
PS For those who didn’t catch it, “HE” is Christ.
