This is waving over engineering an agent with tools, harness, prompts, and loops. The models are still just next token predictors and everything, including predicting more than 1 token, is the result of outside "poking"
LLMs can't and don't "want" anything. If you don't specify a task even the smartest one will just ask you what you want and if you tell it to be creative, you'll get mundane slop.
And yes, you need something to start from, but if you ask it to "do something" and loop it to endlessly ("poking"), you will get some interesting outcomes. So yes you need some initial prompt or task, but that can be "do something" and if you keep asking it everytime it finishes to "do something more". I suspect it will not start saying "no" but rather... it will find some stupid meaning and then drift towards what ever goal it guesses you mean.
I'm unsure whether we agree or disagree on the topic.
