The big difference is LLMs are as big as Social Media and Google in the pop culture, but with a promise of automation and job replacement. My 70 year parents use it every day for work and general stuff (with generally understanding the limitations), and they’re not even that tech savvy.

We haven’t mapped the hard limitations of LLMs yet but they’re energy bound like everything else. Their context capacity is a fraction of a human’s. What they’ll replace isn’t known yet. Probabilistic answers are unacceptable in many domains. They’re going to remain amazingly helpful for a certain class of tasks but marketing is way ahead of the engineering, again.
