If you have ever worked with Terminal Servers, RDP, Citrix Metaframe, or the like (and that's what I have been doing professionally every day for the last 14 years), you will understand the idea of a Thin Client architecture. Thin clients are as old as computing, and some of you remember as I do, devices like acoustic couplers where you can attach a telephone handset to a telephone cradle, so that the mouth ends of the handset and the earpiece ends could squeal to each other. In this way, you could, with nothing but a keyboard and a printer, use your telephone to allow you access to a mainframe computer at some university.

The relevance here is that the client end is thin computationally. It passes nothing but keystrokes and printer instructions back and forth as acoustic codes.

This is what an mp3 file does as well. It passes nothing but binary instructions that can be used by an audio device to vibrate. Without a person's ear there to be vibrated, this entire event is described by linear processes where one physical record is converted into another physical record. Nothing is encoded or decoded, experienced or appreciated. There is no sound.

Think about those old plastic headphones in elementary school that just had hollow plastic tubes as connectors - a system like that generates sound from the start, and the headphones are simply funnels for our ears. That's a different thing from an electronic device which produces sound only in the earbuds.

All of these discussions about semiotics, free will, consciousness, AI...all come down to understanding the Thin Client. The Thin Client is Searle's Chinese Room in actual fact. You can log into a massive server from some mobile device and use it like a glove, but that doesn't mean that the glove is intelligent. We know that we can transmit only mouseclicks and keystrokes across the pipe and that it works without having to have some sophisticated computing environment (i.e. qualia) get communicated. The Thin Client exposes Comp as misguided because it shows that instructions can indeed exist as purely instrumental forms and require none of the semantic experiences which we enjoy. No matter how much you use the thin client, it never needs to get any thicker. It's just a glove and a window.

Hi Craig,

Excellent post! You have nailed computational immaterialism where it really hurts. Computations cannot see, per the Turing neo- Platonists, any hardward at all. This is their view of computational universality.

Computational universality is a standard notion. No need of Plato. Only arithmetical realism, of the kind you need to pay taxes.


But here in the thing, it is the reason why they have a 'body problem'.

Not really. But in fine, yes. That is the result of a proof. No need to present this as obvious, as nothing is obvious in the mind-body problem domain.



For a Platonistic Machine, there is no hardware or physical world at all.

That is wrong. There is one. We can compare to the world we observe, already. And test comp.



So, why do I have the persistent illusion that I am in a body and interacting with another computation via its body?

See the papers and post. That's what I explain. To refute comp you must derive a physical facts from comp refuted empirically.

The physical delusion is the thin client, to use your words and discussion.
