If anyone took a second to read any of this lady's other content, she seems like quite the special flower. Not saying that I disagree with her that you don't need to know everything to be a programmer but she also blatantly lies in the article.

I poked through her github and she definitely knows how to write css. Articles like this make people feel alright with complacency, it's fine to be an okay or new programmer but you should always be trying to improve what you are doing.
