Can AI autonomously redesign my entire website? - RichSnapp.com

Opus 4.7: Smarter, Stricter, Hungrier

Opus 4.7 ships with real coding gains, an automated cyber chaperone, and a tokenizer that can charge you 35% more for the same prompt. The capability curve still bends up. The trust curve does not.

The "U-shaped curve" of cognitive offloading to AI tools

Almost a year ago, I responded here on Thought Shrapnel to what I thought was a terrible paper which claimed to show, via brain scans, that using LLMs was bad for students' cognitive development. As Philippa Hardman notes in this article, the academic literature has begun caught up with what people actually using these tools already know: The theoretical picture sharpened in 2025–26. Favero et al. (2025) warned that cognitive offloading undermines learning outcomes unless the mental effort that’s freed up gets redirected towards other meaningful tasks.
