Life is a special form of complexity: It has the ability to create more complexity and to maintain organization against the tendency toward disorder.

No, life isn’t special in that way. Life exists because of an increase in entropy elsewhere. We don’t consider a planet to be special just because it is bathed in light from its star, but it’s the same pattern: Increasing entropy in the star leads to organization (light) on the planet.

If dark energy means we have an unending input of exploitable energy into the universe then life can potentially continue forever, but there’s nothing special about life that lets it do that.
