The problem is that they are 'everything boxes'. They're the first application that can actually lay claim to being a universal computing aid. What then happens is that people will start using their newfound hammer and before you know it everything becomes a nail, even if for a particular problem there is a better solution you can't beat 'nothing to invest, nothing to learn, get an answer in 10 seconds flat' from a convenience perspective. If I look at the things people use LLMs for I wonder why they take such an unsuitable tool, and then I marvel at the fact that they actually get more-or-less to where they would have gotten with the proper tools, and most likely in less time.

Slide rules displaced tables, calculators displaced slide rules and calculators themselves were displaced for the most part (they are still in use, in education but not nearly as much as they used to be outside of that) by the PC.

LLMs do that sort of thing for just about every information processing aid.
