That's why I said "mostly".
I know they're just statistical models, and that having conversations with them is like having a conversation with a stack of dice.
But if the simulation is good enough to be useful, the fact that they don't genuinely "understand" doesn't really matter to me.
I've had tens of thousands of "conversations" with these things now (I know because I log them all). Whether or not they understand anything they're still providing a ton of value back to me.
