You know what the real threat is? It's not that the NSA will read all your personal e-mails or laugh at you for buying dragon dildos or anime pillows. The problem with them collecting all this data is that it's essentially saving the work of foreign spies. Rather than collecting data on individuals or organizations themselves, all foreign intelligence has to do is infiltrate the ranks of the NSA or compromise the security of their data centers. Who's to say people in the NSA won't be susceptible to bribery or corruption? Or who really thinks they're competent enough to keep everything 100% secure? Some Russian with enough money or know-how could easily get the dirt on someone.
This is the real problem. It's not some 1984 bullshit, it's just putting all your eggs, or in this case, personal information, in one basket.
