"why would I be impressed if I can just go prompt it myself?" I mean, I see what you mean, but this also reads like, "I found out my favourite author dictates their novels rather than types them out and formats them, which is lame; I can just make up stories and speak myself". It's the idea (and to whatever extent, the design intervention during the iterative process) from the human that's most useful and impressive, at least to me.
