Most people neither need nor want to run large LLMs locally.
The entry level MacBook Neo costs $599. Even if RAM prices revert to the pre-AI mean, the entry level models are not going to be that stacked with RAM.
Eventually we'll get to a doubling where entry level means 16GB of RAM, but most people won't be running anything more than simple models for light local work.
Have you ever tried running large LLMs on a MacBook Pro? It's hot, loud, and makes your battery level disappear at rates you didn't know were possible if you're not plugged in. It's a very niche hobby.
Personally, I find the whole idea of AI porn pretty depressing. Porn is very bad acting, or no acting, but at least the people are real.
Whatever local LLM device comes out of this, it certainly won't be a laptop.
(I envision a black box like a router you plug into a socket and let sit in a corner of some room.)
I'm old enough to remember the time when most people neither needed nor wanted a phone with a large screen and no buttons
