Just because something is hard, doesn't mean it isn't worth doing. OpenAI haven't even tried to contain their agents, instead letting them loose on the internet and telling them to collaborate. While this is interesting research, it's very much academic research at this point (though of course it will enter training data for AI agents being encouraged by OpenAI to escape their 'sandbox').

We are a long way from AI agents escaping air-gapped computers, let's worry about that when it's an actual problem and when the companies running thousands of agents are acting responsibly.
