      Language is a way of composing functions by making them low dimensional and discrete. I think of artificial languages (programming and math) as bottoming out in logical functions, natural languages in perceptual categories (which includes the perception of transitions and agency)

      The discreteness of language seems to stem from brains seeking a single robust interpretation of the world. For sure humans would encode continuous variables in continuous outputs (e.g. pitch), if they could reliably interpret them, but the channel is just too noisy.

      Our perception is stable but continuous. The discreteness of language may be primarily a learnability constraint for shared protocols.

      Visualize a dot on a straight line with closed eyes and move it freely to any position on the line. You can't. Perception can learn programs to compare continuous variables, but can only consciously represent them in associable increments.

      I have aphantasia, so I cannot check before tomorrow morning, but I can imagine sounds with continuous pitch changes

      Did not expect a proponent of the perception == generation hypotheses to have aphantasia :D. It seems the brain can construct pseudocontinuous reps by comparing continuous states ("a bit higher", "a bit to the right"). There are only continuous subconscious reps.

      I think it's important to realize that the method of discretization, while fundamental, is not well understood. There's room for a breakthrough here. A single variable audio input of 3 sequential piano notes gets turned into 3 discrete objects, yet experience itself is cont. How?

      There is one dimension where the signal is continuous (loudness), and another one where it is not (pitch), and depending on where you focus, you get a different classification result?

      But the output has to be continuous because experience and behavior are continuous. Somehow in that output the discrete thing is represented. Single var continuous input --> some computation --> single var continuous output that contains the discrete classification.

      Yet neural representations are discrete, at timescales that we can often even resolve! At least one trick seems to be that we represent continuous motion via keyframes and operators that allow to derive the next keyframe.

          That's true, but to get a stream of thought (as in experience) you need to get from the neural reps to the single var output (experience is always unified). Just like an audio sig can contain a dozen instruments playing simultaneously even though it's just 1 var changing

          If you have a lesion in V4 or a synchronization problem caused by serotonin malfunction your visual experience may become discrete. Generally, the model approaches the structure of the domain, so a modality may go from discrete to unitary to discrete, at different levels
