I don't think the answer is to out-compete the machine. It's probably more about being intentional about which efforts still matter to you personally, regardless of whether a tool could do it faster.
The kid learning French and Dutch is a good example actually. He's not doing it to translate. He's doing it to connect with someone. At the end of the day, there will always be things only humans can do, a touch of human spirit. Sorry for being too cheesy
As a precaution I would probably never pass secrets directly to the agent at all. Something like a placeholder format where the actual substitution happens at execution time so the LLM never sees the real value. Keeps things cleaner if something ever goes wrong.
