Quoting Will Durant on the value of summaries and dissemination

Human knowledge had become too great for the human mind.

All that remained was the scientific specialist, who knew “more and more about less and less,” and the philosophical speculator, who knew less and less about more and more. The specialist put on blinders in order to shut out from his vision all the world but one little spot, to which he glued his nose. … “Facts” replaced understanding; and knowledge, split into a thousand isolated fragments, no longer generated wisdom. Every science, and every branch of philosophy, developed a technical terminology intelligible only to its exclusive devotees; as men learned more about the world, they found themselves ever less capable of expressing to their educated fellowmen what it was that they had learned.

…

For if knowledge became too great for communication, it would degenerate into scholasticism, and the weak acceptance of authority; mankind would slip into a new age of faith, worshipping at a respectful distance its new priests; and civilization, … would be left precariously based upon a technical erudition that had become the monopoly of an esoteric class monastically isolated from the world by the high birth rate of terminology.

— Will Durant (1926): “The Story of Philosophy”.

If knowledge becomes overly complex and inaccessible, it can lead to a new form of authoritarianism, with society reverting to faith and deferring to experts as new ‘priests’. As human knowledge expands, the process of making knowledge understandable (to prevent it from being monopolised by an elite class) becomes more crucial and more difficult.
