to make my point easier: for my definition of to read, to understand and comprehend you need a body, an embodied mind. you need agency and consciousness. ChatGPT has none of those, it's an implementation of several matrix functions.
the specific model you are referring to does nothing, it's not acting (it's not reading anything). you have to press enter for it to work. so it's not reading, you (and OpenAi engineers) are doing its actions for it.
