Being precise and skillful with your language has always been important, but in a post-AI world, its relative importance will increase for achieving effective success.
When talking to an AI, the more specific and precise you are with your words, the better the outputs generated will be.
If you express an idea using general words that constitute average thinking and ambiguity, you will get crappy outputs from the model.
If you express an idea using highly specific, detailed words that embed good thinking and clarity, you will get good outputs from the model.
Expressing yourself through words (writing or speaking) is something you need to get great at to do great things. Your ability to express things will correlate heavily with future success.
