It is an interesting essay. It leans on the side of "assistants are useful for simple coding tasks" and it's a bit more critical when it's about writing. The stance is original I find, yes it can help with some writing tasks, but if you look at the writing tasks you can expedite this way... if you wish to expedite them isn't it a sign that they were providing little value in the first place? Is the solution the assistant or changing the way you work? Indeed this might hide some busy work otherwise.
