In response to Rich Hickey's argument that AI is not a tool, a new article asserts that automation and traditional tool use can successfully coexist. The author emphasizes that effectively wielding large language models still requires significant human skill, continuous feedback, and careful judgment.

The article explores how applying neuroscience and psychological frameworks can help overcome the emotional hurdles of decluttering. Readers highlight practical cognitive strategies, such as setting a strict nostalgia budget for sentimental items or mentally evaluating whether they would repurchase an object today. By reframing how we assess our possessions, these techniques make it significantly easier to let go of unnecessary clutter.

Despite early promises of high-density data storage and immersive 3D experiences, holographic technology has struggled to achieve mainstream consumer adoption.
