GPT doesn't understand the questions therefore it can't answer them. It can only generate a bunch of text and make it look like it knows what's being asked. It's not AI, not even close.
What does it mean to „understand it“?
How do you know how you answer a question yourself?
Presumably, what you mean is that you can stop and _reflect_ on what was asked. You‘re aware of it. And if it‘s complicated you might be able to reason and break it down.
GPT-3 certainly doesn‘t do that, but all that means it‘s not conscious.
This can be extended down or wide, with several instances representing different thinking modalities and the final answer being generated from all of them. Basically reproducing a neural net architecture but at the higher abstraction level.
