How can you be so sure? Did you compare in a systematic way or read papers by people who did it?
Now I surely get results giving the llm only snippets and keywords, but anything complex, I do notice differences the way I articulate. Not claiming there is a significant difference, but it seems to me this way.
No, but I didn't need to read scientific papers to figure how to use Google effectively, either. I'm just using a results-based analysis after a lot of LLM usage.
How do we get beyond that?
LLMs have made the distinction ambiguous because their capabilities are so poorly understood. When I say "you should talk to an LLM like it's a computer", that's a workflow statement; it's a more efficient way to accomplish the same goal. You can try it for yourself and see if you agree. I personally liken people who talk to LLMs in full, proper English, capitalization and all, to boomers who still type in full sentences when running a Google query. Is there anything strictly wrong with it? Not really. Do I believe it's a more efficient workflow to just type the keywords that will give you the same result? Yes.
Workflow efficiencies can't really be scientifically evaluated. Some people still prefer to have desktop icons for programs on Windows; my workflow is pressing winkey -> typing the first few characters of the program -> enter. Is one of these methods scientifically more correct? Not really.
So, yeah -- eventually you'll either find your own workflow or copy the workflow of someone you see who is using LLMs effectively. It really is "just trust me, bro."
