Almost all philosophy is incredibly worthless in general, and especially in application to AI tech.

Anything that actually works and is in any way useful is removed from philosophy and gets its own field. So philosophy is left as, largely, a collection of curios and failures.

Also, I would advise you to never discuss philosophy with an LLM. It might be a legitimate cognitohazard.

How exactly do you presume to make an argument about thought and whether or an LLM exhibits genuine thought and intelligence without philosophy?

Not to mention the effect of formal logic in computer science

By comparing measurable performance metrics and examining what little we know of the internal representations.

If you don't have anything measurable, you don't have anything at all. And philosophy doesn't deal in measurables.

How do you know what is, isn't, could be, or couldn't be measurable?

You're not being serious.
