Rhetorical arguments are more important than ever in the age of AI, because AI is our attempt to simulate that. Probabilistic AI mimics rhetoric (inexpertly). It uses past knowledge to predict future behavior (rather, just the next token) based on probability.
To be clear - I'm not arguing that logical argument aren't important; I am a logical person, and prefer logical arguments to rhetorical ones. I prefer the certainty. I still recognize the need for rhetoric. Not everything is certain, and you have to make decisions based on probabilities and unknowns.
