We can build in our lifetimes yes, but truly what life is good at, what it’s designed for, is building over generations. Humans have the strongest ability known in the universe to pass down knowledge, to pass down progress. Consider what the average person’s life was like in 10,000 B.C. Death and danger were surely omnipresent. And while in 2022 we still have serious problems to address, let alone solve, we also have developed language and writing systems, we’ve created technology that makes life easier and maximizes our time. Far less people starve, far more die of old age. We have honed the methods for improvement over generations, over millennia. We inherited this progress, and enjoy its fruits because of the gifts of others. So: what shall we do with all this opportunity, this limited time we call a lifetime?
