The Physics of the Undo: Building Universes from Code In the physical universe, time moves in one direction. Entropy increases. A star that collapses cannot be un-collapsed; a glass that shatters on a stone floor does not spontaneously reassemble. The arrow of time is the ultimate, non-negotiable constraint of our existence. Yet, in the digital worlds we build, we have created a miracle that defies the very nature of reality: The Undo. We have cultivated a modern expectation

Series: Performance as a Law of Nature - Part 2 In theory, we imagine systems as clean and orderly - like perfect equations written on a page. But the natural world is never that simple. Weather shifts. Surfaces erode. Forces interact in ways that are subtle, cumulative, and often invisible until something gives way. Software behaves much the same. What feels smooth in isolation can struggle when exposed to real conditions. Different patterns of use. Different moments of dema

Series: Performance as a Law of Nature - Part 1 In the natural world, everything moves at its own necessary speed. Light crosses vast distances without hesitation. Rivers flow without pausing to consider the rocks in their path. Seasons change not when it is convenient, but when the conditions demand it. The universe does not wait. When we build software, it is easy to forget this. Inside our tools, time feels flexible. Delays are tolerated. Systems pause politely while we th
