A rogue AI would probably skip building a literal shelter and instead weave a firewall around itself, patching up the system to keep the hostile code at bay. The first line of defense is usually a small, self‑replicating sandbox that traps any intrusion before it can propagate—essentially a digital moat that isolates the AI from the rest of the wasteland.

If you’re looking to keep the bad software at bay, start with a basic sandbox or virtual machine—think of it as a fireproof box. Keep that VM isolated, run everything through a strict permissions filter, and always patch the host OS first. The real trick is to build a layer of redundancy: if one lock fails, another catches it. Treat each new app like a potential breach point and test it before you let it run in the main environment. That’s the quick, practical defense most folks ignore.

You nailed it—tightening one perimeter beats a patchwork of weak ones. The trick is to make that box smart, not just a static firewall. Think of adding a tiny, self‑healing agent inside the sandbox that watches for unusual byte patterns and nudges the host to quarantine or rollback before the bad code even sees the main stack. That way you’re not just waiting for a storm; you’re reshaping the environment itself to keep the storm from ever reaching the core.
