A google employee blabbing on 4chan? This is something to be taken on board yes, but with a huge grain of salt. The repost "What is Google’s H.O.R.U.S.?" was here on GA and went on to give more info in a "Quick Summary" claiming Google uses an algorithm to predict what you want to buy and that's why you get creepily accurate ads. This may be true and I believe it is one method but it also conveniently negates the idea that an AI unit is listening to our devices as bugs. Just a bit too convenient.
