I can't think of any less arbitrary scale for comparing civilization advancement than power harnessed. We have the core technologies for interstellar travel now; if we found out our Sun would be dead in 50 years, we'd build it. I don't see any reason to assume that doing so would fail a billion times out of a billion.
