from my perspective it all seems like one big circle jerk, especially considering the hive-mind mentality here on hackernews where working 80hours+ / week for some fun app startup seems like good guidance for young people and something to strive for.
the goal of a startup is to make money, not raising money. the SV scene seems to be concentrating on the latter since its influenced & guided completely by venture capitalists and their interests instead of market opportunities.
to be provocative: just throw thousands of teenagers at random things, give them some pocket money and hope something sticks. motivate them by giving them some grand illusion of being an independent entrepreuner. burnout is just something that comes with the game. give them lectures to clone them into perfect worker bees for VCs as traditional education would clone them into perfect big corp employees.
my advice to young people with drive is: go travel, see the world first. solve real problems. starting your typical SV startup is mostly an illusion and a bad proposition for you. young age is certainly good for coming up with disrupting ideas, but execution profits heavily from life experience - think of survivorship bias and don't be fooled by the few success stories.
