Yep a leader is simply someone people follow.
That’s it. That’s all it is. All the books, leadership courses, etc. are lipstick on that pig. I suppose it can happen, but I’ve never seen someone who is a terrible leader educate themselves into being a great one. It’s pretty close to a natural skill you can build on and develop.
The term has been usurped by the usual suspects, but the definition is still the same on the ground.
LLMs require zero leadership skills. They do require strong management skillsets. These are not remotely the same thing.
I think at some level that "following" bit requires a certain sacrifice or loss of autonomy that people don't strictly have to suffer. And good leaders tend to be able to get people to accept that willingly without needing to invoke authority. An LLM is making no sacrifice, they don't value autonomy so there is no leadership.
