Our brains contain a word salad generator and it also contains other components that keep the word salad in check.
Observation of people who suffered from brain injury that resulted in a more or less unmediated flow from the language generation areas all through vocalization shows that we can also produce grammatically coherent speech that lacks deeper rationality
Here I can only read text and base my belief that you are a human - or not - based on what you’ve written. On a very basic level the word salad generator part is your only part I interact with. How can I tell you don’t have any other parts?
Thus means all you can say about me is that I'm a black box emitting words.
But that's not what I think people mean when they say "world salad generator" or "stochastic parrot" or "broca area emulator".
The idea there is that it's indeed possible to create a machinery that is surprisingly efficient at producing natural language that sounds good and flows well, perhaps even following complex grammatical rules, and yet not being at all able to reason
