The biggest danger of agents its that the agent is just as willing to take action in areas where the human supervisor is unqualified to supervise it as in those where it isn't, which is exacerbated by the fact that relying on agents to do work [0] reduces learning of new skills.

[0] "to do work" here is in large part to distinguish use that focuses on the careful, disciplined use of agents as a tool to aid learning which involves a different pattern of use. I am not sure how well anyone actually sticks to it, but at least in principal it could have the opposite effect on learning of trust-the-agent-and-go vibe engineering.
