We see a minuscule fraction (0.0035%) of the electromagnetic spectrum, meaning our perception of physical reality is already an abstraction. When applied to complex human behaviors, objective "truth" becomes nearly impossible to discern, as it's filtered through cognitive shortcuts and biases.

The brain absorbs 11 million bits of information per second but can only consciously process 50. To cope, it uses "predictive processing," showing you what it *expects* to see based on past beliefs, not what is actually there. We all live in a personalized simulation.

As AI makes it impossible to distinguish real from fake online content (the 'dead internet theory'), society will be forced to question reality itself. This skepticism is ultimately beneficial, as it will lead people to place a higher value on tangible, verifiable experiences like physical touch, nature, and in-person connection, which cannot be digitally replicated.

Modern communication (texting, social media) filters out crucial non-verbal information like tone, pacing, and emotional presence. This has led society to 'hypertrophy' word-based interaction while losing the high-resolution data that prevents misunderstanding and fosters genuine connection.

Our perception is like viewing the entire Twitterverse through a single, highly curated feed. We experience a tiny, biased projection of a much larger network of conscious agents, leading to a distorted and incomplete view of the total underlying reality.

Our experience of the world is a constructed user interface, not objective reality. Like a desktop folder icon that represents complex code, our senses translate raw data (e.g., photons) into simplified, useful concepts for survival. What we perceive is a helpful abstraction, not the underlying truth of the physical world.

A live event with a few hundred people feels more impactful than a dashboard showing millions of users. This is because our brains are wired to appreciate concrete, physical experiences, not abstract data. This presents a core challenge for leaders of digital-native companies to stay motivated and connected.

Scaling a product or system doesn't just make it bigger; it fundamentally transforms the nature of the problems it creates. Jamer Hunt shows how Facebook evolved from a simple social tool into a political weapon as it grew. This demonstrates that solutions for one scale are often irrelevant for the next.

A joystick has 'perceived affordance'—its physical form communicates how to use it. In contrast, a touchscreen is a 'flat piece of glass' with zero inherent usability. Its function is entirely defined by software, making it versatile but less intuitive and physically disconnected compared to tactile hardware controls.
