You're basically saying there's no need to wear a seatbelt because you've driven thousands of times without an accident. Claude is pretty well behaved, but it's not guaranteed to be safe, especially as you start to hit the gas and relinquish more control. Hope for the best, but plan for the worst and all that. Just because your use case doesn't need sandboxing, doesn't mean there's no need for sandboxing.
I'm not having a debate because I'm quite ignorant of the subject. Just trying to learn from you: wouldn't recoverability and observability suffice instead of sandboxing, if such events are indeed rare? not necessarily for all usecases, but for most?
