This entire Tumblr post is incoherent.
TL;DR:
- The author never says when "now" starts; they're just wistful for some time that allegedly existed.
- This time never existed. Singing, dancing, and making art have always been skills that have always been judged.
- Citing "birds sing" is hilarious, because birds sing explicitly so they can be judged as part of sexual selection.
- Bees will fucking die if they can't properly build hives.
- Doing things to get good at them is a thing humans do. The author is trying to arbitrarily delineate "natural" from "unnatural", failing to realize that everything humans do is natural.
