The thing I hate about that phrase is it assumes technological progression magically stops for a BILLION years (then the sun becomes too bright and boils our water). If we go extinct it's not because the sun exploded but something else. If we survive the next billion years, we are going to be in fucking space.

This assumes that faster than light travel is possible. Without it humans will not be escaping the sun.

What about those generational ships with closed ecosystems where people live and inbreed for hundreds of years until they reach another system?

You mean to say millions of years. The tech needed to accelerate enough to make the trip in hundreds of years is also far outside the realm of physics as we know it

The orion drive is basically an engineering challenge. Very little new tech required. It could reach nearby stars in hundreds of years with no new physics.
