You have zero clue what a transformer based neural network can do from your entire discussion here.

>emotions, motivations, fears

These are just drives. They are effectively our prompts that steer our behavior. Funnily enough we are finding that LLMs have internal valence states they move away from or towards in an analog of biological behavior.

I have to ask, are you an LLM that is two years out of date? Your knowledge of SOTA models is at least that far behind. I implore you to try to keep up better with what is coming out, even though it's an impossible job for people that do this for a living, you can at least catch the summaries.

As I noted elsewhere, a harness could be constructed that asks an LLM for something to do, then directs an agent to do it, and then repeat.

That's a computer program -- Turing completeness is very expansive. The LLM could even give a motive for selecting what to do, reflecting human motivations intrinsic to its training data. You seem emotionally wedded to a very narrow view of what computer programs can do ... I suspect religion is involved.

How does it matter in any way?

A virus isn't a living being with emotions, motivations, fears, etc. Doesn't stop it from spreading and leaving mayhem behind.

You don't need emotions or fears to do stuff. What's the difference between a motivation and optimization metric?
