Since LLMs were introduced, I've been of the belief that this technology actually makes writing a *more* important skill to develop than less. So far that belief has held. No matter how advanced the model gets, you'll get better results if you can clarify your thoughts well in written language.

There may be a future AI-based system that can retain so much context it can kind of just "get what you mean" when you say off-the-cuff things, but I believe that a user that can think, speak, and write clearly will still have a skill advantage over one that does not.
