The technological singularity will help us escape the universeThe physical world doesn't matter. What you do matters. How you lived your life will be the same 100 years after you died or a billion, even if people forget you existed, but they physical world has 3 outcomes; big crunch, big freeze and big rip. Your kids won't matter, physical shit won't matter because the physical world is going to vanish one way or another, so imo it makes more sense to live based on non-physical shit like ideals. But hey if your ideal is just to aspire to copy a chav, you do you.
