Taste in coding is a combination of insight, experience, native talent, technical skill, and flair. Tasteful coding produces clever but straightforward minimal elegant solutions that an average developer can't imagine but can adapt and maintain.
This is why "critical thinking" is a meme. Being a critic takes no skill. I want far fewer critics and far more constructive thinking. GenAI being the ultimate constructor is a bonus.
Taste implicitly requires discipline of what one chooses to expose themself to and what not to.
