There's no point at which turning your brain off will work

An essay by Dan Luu arguing against using LLMs with your brain turned off. He observes that starting in early 2025, people began letting LLMs take actions such as summarizing text or writing code and simply assuming the output was correct, without verification. The piece matters to practitioners because it pushes back on hopes that automation reaches a point where checking results becomes unnecessary.

CSS-Tricks could be a co-op

An essay by Eric Bailey arguing that CSS-Tricks, the long-running web design and development publication, could be converted into a cooperative ownership model. Bailey credits the site with much of his professional identity and notes it repeatedly gave him opportunities to write. His underlying concern is that the web will calcify without independent voices sharing practical knowledge, positioning co-op ownership as a way to sustain that sharing.
