This discovery of yours will create forgetfulness in the learners' souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves. The specific which you have discovered is an aid not to memory, but to reminiscence, and you give your disciples not truth, but only the semblance of truth; they will be hearers of many things and will have learned nothing; they will appear to be omniscient and will generally know nothing; they will be tiresome company, having the show of wisdom without the reality. - Plato on the invention of writing in The Phaedrus
Every notable invention associated with language (and communication in general) has elicited similar reactions. And I don't think Plato is wholly wrong, here. With each level of abstraction from the oral tradition, the social landscape of meaning is further externalized. That doesn't mean the personal landscape of meaning must be. AI only does the thinking for you if that's what you use it for. But I do fear that that's exactly what it will largely be used for. These technologies have been coming fast since radio, and it doesn't seem like society has the time to adapt to one before the next.
There's a relevant Nature article that touches on some/most of this.
