LLMs don't have enough context to say No. What might be a very stupid idea in one context may be a fantastic idea in another context. It would be annoying if LLMs refused to complete tasks until you gave them enough context to understand why you are giving them such a task. It's going to take a while before LLM context capacities grow enough to rival a human's.

I do agree that it's a problem but the root cause is the fundamental limitations of current gen LLMs, it's not an alignment problem.
