Agreed. While speaker-independent speech recognition has ever-so-slowly progressed to the point where it only mostly sucks it's probably good enough to log a general transcript. Combine that with the temptation to store compressed audio at 1KB/sec and 1.5GB/year would likely easily cover fully documenting every conversation you have without "somebody listening in." This assumes 2000 minutes/month, way more than I use, but I need to average in females... Divide that by two if you simply log per-conversation instead of per-phone and we're at 0.75GB/year/person. I think we can safely assume that you have privacy only when speaking in-person, and that's if you're not under some sort of investigation. Otherwise, find a windy place outdoors (near a large body of water for dramatic effect) and mumble through your conversation even if you're just a Hipster preparing for next weekend's party.
