I honestly think that AI does accelerate writing work but not in the way you think. Because it eases cognitive burden, it allows writers to create without burning out. Writers like me, anyway, whose day job involves writing cognitively demanding copy about high technical concepts 😅.
In the past, my work to so much of cognitive and creative energy out of me that there's often nothing left for my personal creative work. So I often have to sacrifice my personal writing. But due to the ability of AI to now help me with things that drain me, I can focus things that matter to me.
I like writing so yeah AI is never gonna take that away from me. (That's part of the reason why I don't pay for AI services because I don't really rely on it to generate much text.
(Writers often subscribe to models if they want to generate a lot of text as the free versions do not generate a large amount of text.) The open source Deep Seek is enough for me, because I use it mostly for planning and detail oriented work like editing. I also realize that I like to dictate my writing and I often use AI to help me organize my thoughts. And then I fix it by rewriting it. This has accelerated my blogging and writing.
Oddly I can't do it with fiction 😆. I usually use story beats to flesh out my chapter, and then use AI as a sophisticated swipe file to start my writing. And yes, I still write my fiction with my own fingers!
With that cognitive savings I gained from using AI, I could now write fiction, or my newsletters and #Cdrama reviews without feeling like I am draining my brain dry or burn out every month.
So I think AI doesn't exactly accelerate my work. It enables me to produce more because I no longer am exhausted as quickly or as often.
