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.
