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 Claud Shannon’s framework of understanding information as reducing uncertainty, a light switch doesn’t contain information. But the problem with all kinds of information is that it is dependent on how you subjectively define states and uncertainty. Information is always relative to a certain «perspective».
