I also struggle with this all the time, balance between bringing value/joy and level of craft. Most human written stuff might look really ugly or was written in a weird way but as long as it’s useful it’s ok.
What I don’t like here is the bragging about the LoC. He’s not bragging about the value it could provide. Yes people also write shitty code but they don’t brag about it - most of the time they are even ashamed.
