Anything that processes information is a computer.

The brain processes information.

Therefore, the brain is a computer.

A ribosome processes information. A ribosome is not a computer.

It is under that definition. Not the kind of computer people traditionally think of when they hear the term, like a laptop or desktop, but it’s a computer nonetheless.

Cool. Not sure I can criticise a syllogism. I can try push the definition ad absurdum...
- A light switch processes information. Therefore, a light switch is a computer.
- An OR gate processes information. Therefore, an OR gate is a computer.

Yes re OR gate.

Re light switches: as I understand it, they either inhibit or permit the flow of electricity. But there’s no information there, let alone processing of information. So the example is flawed, I think.

If we use Claude Shannon’s framework of information as reducing uncertainty, a light switch doesn’t contain information. But the problem with all kinds of information is that it depends on subjectively definitions of states and uncertainty. Information is always relative to a certain «perspective».
