A remarkable and sobering new analysis of Internet privacy being released Thursday finds that a majority of the world’s cyber experts believe that keeping secrets on the Web will be “a luxury,” and that the public will eventually accept it as the “new default.”

In a massive survey of 2,511 of the world’s top tech experts, the Pew Research Center found that 55 percent believe that efforts by governments or industry to build a secure privacy infrastructure by 2025 will fail, while 45 percent believe some type of system will be in place.
