Evolution of Communication

Picture a small group gathered around flames as one voice rises above the crackle. Every eye locks on the speaker, and when someone laughs, the whole circle feels it. Questions flow freely because there are no barriers, no intermediaries, nothing standing between human and human. This was not just communication. This was communion. 3

The storyteller read faces and adjusted in real time, turning listeners into active participants who shaped the story through their reactions. Physical closeness created trust before a single word was spoken. Eye contact meant accountability, shared emotion bound the group together, and by the end, everyone carried the same experience. 4

This was the first time a message could outlive its maker. How do you communicate when you cannot be in the room? Early humans answered by painting on stone, creating images that would reach audiences across 40,000 years and countless generations. 5

But the painter was not there to explain, and no one could ask questions. Voice and gesture vanished entirely, leaving communication as a one-way broadcast from creator to viewer. Reach grew dramatically, but connection dropped to 65%. 6

Visual storytelling reached massive scale, but with a catch. The Bayeux Tapestry tells one version of the Norman Conquest: the version the winners wanted told. Churches commissioned murals and kings funded tapestries, flooding public spaces with large, colorful works that spoke to anyone who saw them. 7 8

The problem was that power now controlled which stories survived. Only approved narratives persisted, and you could look but never question. Institutional control gained ground while genuine exchange vanished, dropping connection to 60%.

Something interesting happened: the blackboard arrived and connection scores actually went up. Teachers could draw and erase while students contributed, allowing ideas to emerge in real time as the presenter faced the room and adjusted based on confused faces. 9 10

Erasability enabled real-time adaptation, letting teachers add, erase, and reorganize on the fly based on how the lesson was landing. This made presenting interactive again, and connection recovered to 65%. It was a brief renaissance. 11

This was the first time screens commanded our gaze. The magic lantern projected images painted on glass onto walls, lit by flame, and suddenly visual content captivated attention in ways that made lectures riveting. 12 13

But notice what happened: the lights dimmed and the speaker became a voice in the dark. Every eye focused on the screen instead of the speaker, and audiences started preferring content to connection. The score fell to 55%.

Hold your questions until the end. Kodak's Carousel held 80 slides in a circular tray, and the rhythm became mechanical: click, advance, click. Slides were made weeks in advance with no changes allowed during delivery, and while polish reached new heights, flexibility hit rock bottom. 14 15

This format gave us a phrase that still haunts meeting rooms: 'Please hold your questions until the end.' The presenter now served the presentation rather than the audience, spontaneity died along with adaptation, and connection hit 50%.

Spontaneity was traded for structure. Overhead projectors became standard for sales meetings, and while you could theoretically write on transparencies in real time, most people used pre-prepared sheets instead. 16

The projector became a physical barrier between speaker and audience, splitting attention between screen and person. Preparation replaced improvisation, and for the first time, connection dropped below 50%. Score: 45%.

The slide becomes the message. PowerPoint arrived in 1987, and suddenly everyone could make slides. Bullet points multiplied while animations distracted, and the deck grew from supporting tool to starring role. People stopped preparing to present and started preparing slides instead. 17 18

Edward Tufte called it the 'cognitive style of PowerPoint': complex ideas fragmented into oversimplified bullets that stripped away nuance and depth. Presenters became slide readers while audiences became spectators, and the score dropped to 35%. 19

Together but alone. In 2020, every meeting became a grid of faces in rectangles, and your brain now works overtime trying to read people through compression artifacts. Natural social rhythms break down while casual conversation dies, leaving everyone technically present but emotionally distant. 20 21

You are literally not present. You are a small rectangle competing with email notifications and browser tabs for attention. Trust used to be built through quality time in person, but all of that has changed. 85% of connection lost. Score: 3/20. 22 23
