Your comments imply that you derive self-worth from external validations, i.e, my effort has no worth if someone else can do better.
I think this is an unhealthy world view. I've certainly learned thus after years of therapy. Others derive self-worth from self-validation.
We'll never be fast at math as calculators, yet their exist people who enjoy doing head-math. Doing a jigsaw puzzle has no inherent worth, yet people love doing so. Those people exist so it's a good idea to try to understand their perspective.
Not everyone's idea of fun is "Creating value for others"
Guns are great for hunting, but people still learn archery, because it's fun to shoot an arrow.
Another aspect is human connection: I would prefer eating an average meal made by someone close, rather than an amazing meal made by machine. Machines can't add the special ingredient of love :)
I would love to learn blacksmithing, for the sole reason that forging a sword from an iron/steel ingot is so fucking metal and awesome.
