I'd seen this excellent and fascinating presentation -- I think I posted on Twitter last year -- but didn't (consciously) mean to steal your title, or nearly!

This discussion has profound implications with regard to Santaya’s famous quote: “You have the happiness of knowing that, when nothing of value endures, the earth may still sometimes, because of mankind’s efforts, cast a slightly different shadow across the craters of the moon." - Santayana.

Although it was only minimally reassuring, based on your argument, even that shadow will not endure when mankind is gone.
