Technology is deeper than you think

I’ve said before that I don’t think Facebook is listening to you through your phone, but the truth is perhaps much worse. The amount of detail (and information they can derive from that) is staggering.

This crazy technology can be a good thing, too. I’ve thought for years that companies like Apple would find a way to monitor things like blood sugar levels with non-invasive sensors, and it seems it’s finally on the horizon. That’s been on my mind ever since I saw this crazy device that can check the safety of drinking water from outside of the cup. Neither of those technologies is perfect yet, but the fact that they exist means perfection is coming.

This kind of “crazy” tech goes back much further. From the book Sapiens came this gem from World War Two:

During World War Two, BBC News was broadcast to Nazi-occupied Europe. Each news programme opened with a live broadcast of Big Ben tolling the hour — the magical sound of freedom. Ingenious German physicists found a way to determine the weather conditions in London based on tiny differences in the tone of the broadcast ding-dongs. This information offered invaluable help to the Luftwaffe. When the British Secret Service discovered this, they replaced the live broadcast with a set recording of the famous clock.
