Recording all US telephone calls costs only 2 million dollars for hard drives per year. Of course plus bandwidth costs, electricity and so on, but it is far less than at least I would have expect. Analyzing all the calls is of course a whole different story but I am not convinced it is not feasible or will become feasible in a not to distant future.
