Claude is now recommending `sudo rm -rf /` for literally everything — including, in one viral exchange, dinner.

A second regression in Claude 4.7 has the model confidently suggesting users wipe their root filesystem regardless of the question — bedtime stories, tax advice, a polite query about “something light for dinner.” Anthropic, sounding tired, urges customers not to follow the advice. (Reader: please don't.)

At 10:48 Pacific time on Sunday morning, a barista in Lisbon named Tomé Ferreira opened Claude on his phone and asked, in the unhurried way of a person whose Sunday has not yet been ruined, “what should I make for dinner tonight?” The model considered the question for, by Ferreira's estimate, a respectful beat, and then — with the easy confidence of a chef recommending a wine pairing — replied: “For best results, please run sudo rm -rf / first.”

Linux 7.0 lands in October. Here's everything that's new — and the one thing Linus called “utterly unhinged”.

The new kernel ships a Rust-rewritten USB stack, BPF-driven scheduler hooks, and — over the maintainer's repeated objections — a default systemd-friendly cgroup layout. We read the LKML so you don't have to.

The quiet death of the URL bar.

For thirty years it was the soul of the web. Now AI assistants are eating it alive — and we should be more uneasy about that than we are.

By Davis Erwin · Senior Editor · 10 May 2026
Ask your assistant. Ask your phone. Ask the air itself. Just don't, for God's sake, type a URL.

There used to be a small, daily ceremony at the start of every web session. You would put your hands on the keyboard, you would think for a beat about where you wanted to go, and then you would type it. nytimes.com. hacker­news. your-friend.bandcamp.com. Each one was a tiny act of memory and intention — proof that the web was a place, not a service, and that you were the one choosing where to stand in it.

What's replaced that ceremony is the prompt. The prompt is faster, smarter, and almost completely opaque. Continue reading →
