People get upset because Twitter and Facebook &quot;mess with&quot; their timelines, as if they were some fundamental natural component of the universe. The average person, even a young &quot;digital native&quot; has no concept of how their gadgets work, so while you might think &quot;Oh, this pretty much has to be sitting on their server in a recoverable format&quot; the average person thinks the picture lives only on their phone. They can&#x27;t even get to the point of making an informed decision of whether or not the data they give up is worth the service received because they lack the models to understand what happens.<p>It&#x27;s like wondering why someone who still thinks good and bad humors mediate health isn&#x27;t worried about their cholesterol, there&#x27;s literally not the machinery available to make that a concern. This is one of the biggest reasons that we should teach coding in schools. Even if you never write a line of code in anger, knowing vaguely what&#x27;s going on at least gives you a chance to be a consenting participant in technologically mediated arrangements.
