I've noticed that when I speak I really don't control each word. I have an idea that I want to convey, but how each word comes to my mind as I form a sentence has always felt like it's controlled by an unconscious algorithm. So I don't understand why people find this prediction mechanism so alien. It isn't clear to me how much of communication is really in our control. With the current tools, it feels like we still provide the ideas we want the AI to convey, and it may be using a nearly identical mechanism to us to form the words. Consciousness would be the computer being able to come up with the ideas. So, it seems to me we've gotten close enough on the communication side of intelligence. But the machine is not conscious. When it is, it seems like it will generate its own ideas. Are people debating whether the machine is conscious? Otherwise, it feels very straightforward to grasp what we've made up to now.
