This was my reaction as well. It seems that looming existential threat the tech industry is currently grappling with is a direct result of the laissez-faire idealism of the early internet pioneers. Obviously the internet is a net-benefit to the human race but we really should learn from our previous mistakes. I'm not sure what the solution is but we shouldn't pretend that there won't be some criminals and terrorists among the ~3Bn people who suddenly find themselves connected.
