The thing that's so odd to me here is that she's giving advice as someone currently in the situation she's advising on, in fact, just embarking on this path. This article might be totally different for her if she was a 25 yo dev who skipped school, or 30 yo, etc.

It's a well reasoned article, and I don't know how useful having a degree is for CS. It doesn't seem like she's in a position to have the self-awareness of her position, let alone to advise others on it.
