I just don't get the fear at all. I too have 10 to 50 agents working 24/7, from 5+ different providers. They talk to each other directly using tmux send keys. What is the exact frightening thing here?
It is all tokens following tokens.
That being said, the danger is measured in computer damage, which can be a lot personally and to a company, but less existential, so your mileage may vary as to how "scary" it is.
What scares me are the people who think that this software is the equivalent of an perfectly-smart elf in a box and use it blindly.
