Full disclosure - my background is in operations (think IT) not AI research. So some of this might be wrong.

What’s marketed as AI is something called a large language model. This distinction is important because AI implies intelligence - where as a LLM is something else. At a high level LLMs are using something called “tokens” to break apart natural language into elements that a machine can understand, and then recombining those tokens to “create” something new. When a LLM is creating output it does not know what it is saying - it knows what token statistically comes after the token(s) it has generated already.

So to answer your question. An AI can hallucinate because it does not know the answer - its using advanced math to know that the period goes at the end of the sentence. and not in the middle.

They randomly started turning up in my music recommendations (I mostly listen to metal). I was so confused and so happy about it…

I’m of the mind that it can involve a screen - but needs to be a different part of your brain. For example 3d printing, writing, reading a (digital) book. However if you are nearing burnout, you need to pick up something radically increase your non work time, and spend your free time doing something that does not require a screen.

The cynical side of me? More monies.

The charitable side of me? Pathfinder/5e don’t do what they want out of a system.

Funny how critical role is making it’s own system…
