Ex-Facebook president Sean Parker: site made to exploit human 'vulnerability'

Site's founding president, who became a billionaire thanks to the company, says: 'God only knows what it's doing to our children's brains'

Facebook's founders knew they were creating something addictive that exploited "a vulnerability in human psychology" from the outset, according to the company's founding president Sean Parker.

Parker, whose stake in Facebook made him a billionaire, criticized the social networking giant at an Axios event in Philadelphia this week. Now the founder and chair of the Parker Institute for Cancer Immunotherapy, Parker was there to speak about advances in cancer therapies. However, he took the time to provide some insight into the early thinking at Facebook at a time when social media companies face intense scrutiny from lawmakers over their power and influence.
