William Binney, former technical director of NSA disagrees: https://www.youtube.com/watch?v=3owk7vEEOvs
I see further down the thread you claim that surveillance data is deleted without ever being looked at. Must be why they need a half dozen gargantuan datacenters full of storage and compute.
This is the correct point of reference, but you are misinterpreting it and I urge you to think about it again. All of the government's facilities put together amount to almost nothing in the data center landscape, therefore it should be quite obvious that they certainly are not equipped to broadly intercept, store, and search "everything".
Unfortunately Binney has absolutely lost it and can’t be considered credible.. literally hanging out with Alex Jones and talking about Stolen elections using math a precocious middle schooler could rebut.
His pinned Tweet is still referencing a “directed energy weapon” assassination attempt of him by the US Air Force (which took place during the Trump administration, who he was supporting, so apparently some rogue DEW plane or deep state operative?)
