Humans already revise and refine their thinking. Tools just compress that process and help filter signal from noise. The meaning still originates with the person.

This is assuming that an extreme majority of people use the tools this way.

Consider a much more cynical view where people are strictly self-interested and use these tools to garner engagement and self-promotion. Good chance the meaning did not originate from the person. And now these people have tools to outsource their parasitic intentions.
