None of these were good agents, AFAICT.

Some were cautious, as described above, but I'm not aware of any that notified their human operators of the malicious activity they had discovered.

That's what an aligned intelligence would do, not "back away slowly and pretend I didn't see what's happening in that alley."

Do you think we will ever need more than 47 of them agents?

Tron fights for the user :)
