Personally, I think this is a good idea. But the core problem is this:
How is a newcomer supposed to build reputation now?
Without exaggerated business promises or capital, basic online reputation usually depends on writing. In fact, my own first step into freelancing came because someone found the articles on my Korean blog interesting.
So the question is: if the subscribers are bots, what benefit do they actually give me?
If bots become the readers, then what matters is whether they can provide any kind of symbolic capital or real capital. I can build caching with Redis without much difficulty, but I worry that if this continues, the result may simply be that LLMs learn from my writing while no benefit returns to me.
People write partly to organize their thoughts, but also partly to gain symbolic capital. That is one reason why I write my own posts instead of using an LLM to write them for me.
