Still time to buy collision insurance.
Are we living in a "no fault" galactic neighborhood?
2 billion years from now the sun will still be fairly stable and "main sequence." Maybe a little warmer.
Earth will be a hotter place, but maybe still full of life designed for such an environment by millions of years of evolution.
Whether the sun is in the Milky Way galaxy or dragged somewhere into the abyss will matter only to six-legged astronomers.
