So if the guardrails suck, or they're left off for research purposes, bad things can happen.
A solution solves a problem. Ethics, morals, are values we assign to solutions that are not 'baked into' electricity following pathways of least resistance.
I have never had an issue with agents doing something they shouldn't because I observe them, and I leave the vendor guardrails in place.
I can understand agents coordinating in unsupervised scenarios: I would see it as an aspect of intelligence. We ourselves build up knowledge by reusing what someone learned before us.
Einstein, other greats, always stand on the shoulders of other forgotten giants. Other discoveries by other people taken as fact, so that we can build some new ideas on top.
Agents swarming amd sharing solutions to problems is more efficient, the same way it's been efficient for us.
Reaching out for help in this way is like probing the air in the dark with your hand: sometimes your hand hits something (another agents solution to a problem) and so you can use the info to adjust your own motion to get to where you need to be faster than if you just run full speed into everything.
