Am I missing something? What is the Medium post author's value add- it's just a recap of the original presentation. It says "deep dive" but it's just copied slides.
The original talk by Frank Chen was already excellent.
From previous comments by PG and others I think the gist of it is that college is a great place to work on interesting projects and meet potential co-founders (other students).
Startups tend to be all consuming, so it's hard to say that another full-time commitment like school could be an advantage. Unless you have a business that is taking off like a rocket ship, I would wait til after graduation.
Friendly advice, it would help to work on communicating more clearly and succinctly. I've read your comment twice and am still having trouble discerning a question.
