I think scale matters but it's something that can be traversed. That would be the point of transhumanity. Presently, our species is too weak and myopic to matter on a cosmic scale, although we do matter on a terrestrial one (given the Anthropocene). But we can imagine evolving into a Type III civilization on the Kardashev scale, in which case our deeds would be woven not just into the geology of Earth, but the evolution of our galaxy. So the scale of human consciousness can change, depending on whether elite countercultures can take hold of mass awareness.
