Human communication and reasoning is the end result of billions of years of evolution. I'd be very surprised if LLMs can fundamentally alter it in a few years. When considering phenomenon like these, I think people seriously underestimate what I'd call the "fashion effect". When a new technology, medium or aesthetic appears, it can have a surprisingly rapid influence on behaviour and discourse. The human social brain…
Think of all the things that took hundreds/thousands/millions of years to develop and mature, which humans have managed to destroy in relatively short order.
