That's impressive, but it isn't thought, anymore than neurons in a dish that learn to play Tetris have thoughts, or if you spent eons painstakingly calculating what the TPU did with the model to come up with the same output tokens, but via pen and paper instead.
When the TPU does it, is the TPU thinking? Where does the critical thinking take place in the endless pages of matrix math that eventually evaluates into the same token output as the TPU?
