Is building a palliative AI companion for people with dementia ethical?

It's not unethical if it's an assistant that enables the user to live with greater comfort and ease. If it helps with recall and memory, with appointment-setting, with planning, or simply if it serves as a companion which suggests books and movies -- it's really the opposite of unethical.

What it shouldn't do is give specific advice on medical matters. Even if it's no worse than a doctor, or even better than a doctor, 9 times out of 10, that one exception could cause serious trouble. Unlike regular Chat-GTP users, people with dementia are already quite sick, are (usually) already on medication, and require more thoughtful care.

More importantly, it shouldn't be capable of mimicking a living or dead person. You'd probably need to hardwire it so that it has a name and "personality" of its own, which can't be changed by the user.

It all depends on what its goal is. As a caretaker that serves as something that aids with their memory then I say yes. But as a companion type that helps the emotional side then I say not yet or no. LLMs are too prone to hallucinate randomly and there's really no there there. It's an empty bunch of words. It has no memory or feelings yet the person who has dementia is a full human being who falls in love and has feelings for other beings. Helping someone fall in love with or have feelings for words is not ethical in my opinion.

So you want to use a technology that's known for hallucinating and give it as a companion to people with reduced cognitive abilities?

What could possibly go wrong!

As a follow up, you could branch out into hardware and give skateboards to people with Hemophilia, or paragliders to vertigo sufferers.

Why do you suspect it is not ethical?

>What features could make it more ethical?

You should think the other way around, start with an ethical base, and only add features that keep it ethical.

Easy to maintain for a decade or more of use. No dependency on remote servers subject to the whims of another company.

What would make it unethical?

Wouldn’t addressing those concerns make it ethical?

Anyway, things are either ethical or they are not. There is no “more ethical.” (but there are things that are outside ethics, what a red shoulder hawk does for example).

One approach would be to address its use in a living will while the future patient can make an informed decision for themselves.

Good luck.
