Given we've got about 7.5 billion years until the sun burns out, and about 1 billion years before anything may become completely uninhabitable, it's pretty unlikely either new technology or space colonisation won't have happened before then. I mean, for comparison humans have been around in a modern form for about 50,000 years... well the chances of something not happening then are few and far between. Probably could have launched millions of generation ships between now and then.
