I mean, how can you say that he didn't think it himself? I thought this same thing and realised apparently I'm not the first. You have no idea how many of my blog posts ideas have come in HN first before I could publish. People can have the same thoughts. And have em all the time as well.
Psss.. See how @sm-silversight who commented on your post said the same thing I did? That's realtime example right there.
Coming back to the topic at hand. I agree with the OP. If you don't care to write it, why should anyone read it? AI has good usecases. But am not sure writing is one.
Writing is not just about the end result. It's also about the thought process. I learn about the topic more as I write. I correct my incorrect understandings as I write. When am pissed, my article has a different tone. Am rude, too direct. When am content/happy, different one. All of this is sterilised into something robotic where the author won't even remember what he/she wrote? What's the to like? For brownie points?
