Well, the agent should help you by saying "hey, I cannot do this task, but I can bypass the problem by doing this, but obviously it is not something you intended me to do or even something you were aware of, so I will not do it unless you tell me explicitly it's ok".

It's win-win: the agent is helping and it is educating you about things you obviously did not realise.

That works great if it's one agent, absolutely doesn't if you want to tackle something complex that warrants using ..say.. ten agents.

I can imagine a future where this technology empowers you to do things with a thousand agents.
