Why Write?
Why write an essay when you can type a few words and have AI generate one for you?
That post does a great job at answering this not-so-simple question:
@jeremy Lots of really good points, but I'm finding it invaluable in writing my daily photo blog posts.
It takes as long, because I describe the photo, and the outline of what I want the blog post to say, and then I go and edit the post so it doesn't sound totally flowery.
I agree that attempting to explain something in words will very quickly make you realise you don't know the subject. :)
