Considering I went through a phase before I started using Claude Code where I'd eventually reach a point where I'd mindlessly approve ridiculously long command chains, I believe this.
As the article writes: "many users are clicking through reflexively rather than reviewing each command".
It's far better (for my working style, anyway) to have some external isolation/sandboxing, but leave the actual command approval to LLM.
According to them - for things they care about.
