The only thing I would consider myself to be an expert in is writing code.

I know how LLMs work (and have since the 70s - they haven't changed since the 50s, the only difference is scale).

I know a lot more than most people about Astronomy and Physics in general (I can even manage Quantum Physics to a point). I stay up-to-date on that stuff.

Pretty good on music history and theory (though Western cultures mostly).

And historical costume (I can look at a dress and not only tell you the period and probably the country). I know what people wore and why.

I'm not a specialist in these things by any means, but I know about them, or know where to find out.
