Of course there is nothing dehumanizing per se in the use of a certain type of communication medium. A text message from a loved one that is far away and that one misses dearly is much more meaningful than small talk about the weather with a stranger we are face-to-face with while waiting for the elevator.

Life is not so simple though. What terrifies me about naive techno-optimists is how they shrug their shoulders and bypass incredibly complex issues, for which entire scientific fields, philosophy, works of literature and millennia of thought and experience exist, with some super-simplistic tech analogy. As if it all boils down to superficial things such as delight, profit, user experience, "quality of interaction", information exchange, "retina display", touch-this-or-that, etc etc etc.

It doesn't. The medium is not just some inert thing, not just a tool. New technologies that create new mediums tend to profoundly change society in ways that were not envisioned by the inventors of said technologies. We can talk about how the printing press led to Protestantism, or how TV changed family structures, political messages and even styles of war.

A social network app comes with a lot of things attached, not least among them a company seeking rapid growth by selling ads. To sell more ads, they do two main things: they try to know more about their users so that they can target the ads more precisely and they try to change the user behavior so that they spend more time interacting with the app. The well-being or own interest of the user are not factors in that equation. Entire dimensions of freedom are disappearing with this new type of interaction: the freedom to be alone, the freedom to set your own social norms (with whom do you feel comfortable swearing or telling offensive jokes), the freedom to have an intimate conversation without worrying about the possible existence of a precise log of this conversation god knows where and under the control of whom, the freedom to express a political opinion in public without worrying about what a potential employer might think about that one decade from now. The freedom for kids to spend time with no adult supervision, learning how to be autonomous and discovering their own identity! Or to have a place to retreat from bullies, instead of being exposed to them 24/7.

Yes, it is dehumanizing to have our communication channels and mediums being gradually and inexorably replaced by new ones where a powerful third-party is always listening, always present, always making small tweaks to subtly guide us to behaviors that they would prefer we adopted. Always setting the rules of our private interactions, of our most intimate things. Maybe they think this is all quite invisible but it is not. More and more, even the technically naive can feel their presence, and it has a chilling effect on culture and society.

I love technology, but I love it for what it is. Technology is neither good nor bad, people do good or bad things. Technology is a power amplifier, and some technology that is so powerful that allows for things so good that one could only dream of before, normally also allows for things so bad that one could only have nightmares about before. Case in point: going to the moon vs. intercontinental ballistic missiles. And side-effects we are not intelligent enough to foresee, because we are not intelligent enough to fully understand such levels of complexity. So we have to remain eternally vigilant, distrust simple solutions and slogans and try to educate ourselves and others, instead of embarking in childish, simplistic optimism. This is all very serious business. Ask the inventor of the web what he thinks about how things turned out.
