AI models don't "understand" anything.
A popular sentiment, it seems. Can you please explain what you mean by the word in scare-quotes?
What is the intended point? I really can't understand what you mean, and I'm human.
Human understanding comes in degrees, from the trivial to the profound. Its not a binary thing. So I'd have thought the question is how much does an AI understand, what is the depth? For example, I often just need the AI to understand my question sufficiently to look up the answer. It does not need to understand the answer if it is common one. If it is a simple and common question, recognition can count as understanding.
Parent post is obviously using the word in a different sense. Does he actually understand that sense in a way that can be explained, or is it just a gut feeling?
