One common conclusion is that since "things" do not last, our real investment must be in "people" in the lives and loves of family, friends, community, etc. Fair enough, but the point here was never to start knocking what we do with our lives in the first place. This isn't about "materialism" or "ambition." It's simply an observation that pretty much anything we do will vanish at some point.
Even if we focus totally on people, and then measure it by all our ancestors and all human history to come after us. Whether we strive for humanity of the future to become more loving, more open, enlightened, loved, whatever, none of them will last any of the destructions listed here either.
Make it a tower of people and it's a still a tower that's coming down some day.
