Things, to be and the computer metaphor

From birth, we learn to communicate through language—but language misleads us. It convinces us that we truly know what things are, that we comprehend the abstract essence of a thing. This illusion shapes how we think about the mind: we imagine it as a cognitive thing that can be explained and replicated within the computer metaphor:
input a thing → cognition as manipulating things → output another thing.
Our own introspection reinforces this metaphor, even as it fails to reveal what is truly happening within us. Yet despite this failure, we persist—because abandoning the computer metaphor is almost unthinkably difficult.
