I can see legit use cases where people simply can't communicate in any physical way. People with locked-in syndrome, etc.

But, obviously those only make up a small number of people.

Strapping a mind-reading machine onto some detainee is probably the more likely case.

It’s fairly common for gifted people to struggle to communicate when they’ve made a multi-step inference in their heads. Whether this technology actually allows them to express themselves at the speed of (excited, fully focused) thought or not, I can see how the possibility of achieving that is exciting.

Sounds like a lot more work than just teaching communication skills.

Military sci-fi is full of mind-machine interfacing like this. There’s definitely value in being able to interface directly with a machine instead of having to push buttons or read outputs.

The problem is that anything based on LLM architecture is not going to be fast or accurate enough to allow someone to, say, fly a fighter jet with this interface.

This might be naive, but I think the idea is to replace your keyboard

Sure, but the author takes it much further than that. She wants to have the AI write into her brain as well as read from it.

that replaces your monitor.
