64 billion bytes at 2,000 per second is 32 million seconds, or 1 year to scan the entire contents of RAM once. Obviously data and processes are going to bounce around in that year, so just peeking randomly and naively at your RAM, the chances are perhaps slim, but not "end of time" levels of slim. Randomly probing millions of different targets, the chance of finding something of value is much higher.
