Martin Luther used it to spread his influence extremely quickly for example. Similarly, the clergy used new innovations in book layout and writing to spread Christianity across Europe a thousand years before that.
What is weird about LLMs though, is that it isn't a simple catalyst of human labor. The printing press or the internet can be used to spread information quickly that you have previously compiled or created. These technologies both have a democratizing effect and have objectively created new opportunities.
But LLMs are to some degree parasitical to human labor. I feel like their centralizing effect is stronger than their democratizing one.
