I'm curious what facts you're talking about. The very problems you point out about healthcare.gov support part of the author's argument - that today's tech environment rewards the creation of a sexting app over more groundbreaking work, and therefore youth do the former.
From my perspective, at least, few of Silicon Valley's startups will have a lasting dent in the human world. Funding for spaceship technology is limited, more people are working on note-taking apps than cleaning the air, and the hype is all on Snapchat (which does have a huge valuation).
The real issue is how we change it; change inevitably comes from youth. And if today's youth come out of college excited about sexting apps, I have little trust in a better future. That being said, I'm not in a position to say much, being a college student myself.
