> The only way for a tool to escape a sandbox is if you built a crappy sandbox

Well, sure, but typical software-level sandboxes are crappy at an alarmingly high rate, either on this access or the usability access. Languages like Python are fundamentally not designed for sandboxed interpretation; any Bash tool is at least as insecure as all of the vulnerabilities in all whitelisted executables.

I'm arguing for hardware-level measures on basic defense-in-depth principles. Like, such a huge part of the reason why we're even doing this AI research is to find vulnerabilities, so it's insane to have a test environment that doesn't start from the premise that there are vulnerabilities. In everything.
