I think that many of us are more susceptible to biohacking than we think. The clip that I've shared of Harari talking about how our data is being obtained to learn about us reminds me of my visits to the eye doctor. When my optometrist is trying to help me determine which prescription will help me see clearly, he runs me through a series of "tests" in which I am asked repeatedly to indicate a preference to let him know which picture he shows me is the one that is the clearest. "This one? Or this one?" We go through that process until the eye doctor is best able to determine how to manipulate my vision through prescription lenses so that I can see clearly.
Just as my eye doctor takes the input I give him to know exactly how to apply the changes that are needed in order to change how I see things, our data is being collected and used by those who want to change how we see things. But instead of us being cognizant of the "testing" that is being done on us, we often are unwitting participants in the experiment. I don't think there is anyone who would deny that our data is being collected so that it might be used to steer us. That is something that isn't new, particularly with regard to advertising of products. But what Harari is talking about is something that moves us beyond having our information simply used to target us for the advertising of products. It goes one step further (at least) than simply putting a product in front of you that the data suggests you will like. It also puts in front of you other information, often as sponsored content or suggested content or other targeted advertising that sneaks it's way in as if it were suggested by a "friend," or perhaps because a "friend" of yours liked it also.
As Harari says, the goal is to keep people plugged in to the technology for as long as possible, because that is how people are able to be influenced and distracted--and the more time we spend engaging with technology that interacts with us in such a way, the more it "knows" who we are. Those who are collecting the data who are being given a clear picture about who we are. As Harari says, having that kind of knowledge about people is where power and control is now to be found.
I know people who predict that the future will play out in ways that they believe will model historical events of the past which seem similar. With regard to some things, I am sure that there is truth to that; however, I think that we would be wise to take heed of the warnings of Yuval Noah Harari when he says that the influence that today's technology presently has on our lives (and even what is coming down the road with regard to the move toward transhumanism) make it impossible to predict the future based upon the past.
