For centuries the American tradition was to work to create for the next generation a world better than their own.
The trend held up fairly well, for a while.
It may be comforting to imagine an infinite future which unrelentingly trends toward improvement.
But astronomers predict that when our sun, our white dwarf star goes red giant, it will subsume Earth's orbit, and life on Earth will go from medium rare to well done.
Even if we find refuge in another, younger solar system, that refuge will (on cosmic scale) only be temporary. For cosmic heat death is inevitable.
Whether we'll still be biological by then, some bio/artificial hybrid, or whether fully artificial, the end will be near.
Food or fuel would have to be produced artificially, and with the convenient energy flux of stars all gone, our power source would soon be exhausted.
Therefore:
is it not all for naught?
Thus the topic question.
What is your fundamental motive for doing what you're doing right now? "Why Bother?" if it's all ultimately futile?
