Sometimes I think the world itself might be one enormous harness. Throughout human history, there have been periods of major invention and technological breakthroughs, followed by periods where the knowledge produced by them is combined, organized, and eventually compacted so that the next generation can continue from where the previous one left off. In a way, this feels similar to how an AI harness manages context over a long-running task. When one context can no longer carry everything that came before it, the important parts are compacted and passed into the next context. The next context does not begin from zero. It inherits a compressed representation of the work that has already been done and continues from there. Civilization seems to work in a strangely similar way. No generation can carry the entire context of human history with it, so knowledge is continuously compressed into language, mathematics, scientific laws, engineering principles, institutions, tools, and technologies, and that compacted context becomes the starting point for the generations that follow. From there, another period of application and deployment begins. Existing knowledge is recombined and applied in new ways, and through those applications we encounter things that were not contained in the previous context: new problems, new phenomena, new laws, and new unknowns. That expanded context is eventually compacted again and passed forward. So perhaps history is not simply a sequence of inventions. It is also a continuous process of context expansion and compaction, with each generation inheriting enough of the previous context to push the frontier a little further. What is interesting about AI is that this process no longer has to happen only across human generations. Harnesses can already expand context through work, compact it, pass it forward, and continue the process again. Perhaps what we are beginning to automate is not just intelligence or labor, but this loop itself. We may already be entering an automated singularity.
