'Should' and 'will' are far apart when we're talking Galaxies :)  I listen to Star Talk all the time, btw.  Even Tyson would admit that he can't say for sure.  Not that I'm saying for certain it will happen, all I'm pointing out is when you're talking billions of years, many, many unforeseen events can occur.  Heck, a star going supernova at the right angle would potentially strip the atmosphere right off the planet and irradiate all life on Earth.  The thought that we'll definitely be around in 5-7bln years is...well, human levels of ego talking :)

Yeah, I have little doubt humans will be long gone is 5 billion years. Even if our genetic line survived we'd have evolved to much as to be unrecognizable. But I get what you're saying, tomorrow NASA could announce that they've found a giant meteor flying towards Earth and we could all be gone this time next year.

Yeah, exactly.  There's just so much unknown that can happen in 100,000 years, let alone a million or a billion.
