What is most characteristic about human intelligence is the ability to abstract from particular, concrete instances of things we experience. This allows us to form general concepts which are the foundation of reason. Analysis requires concepts (as concepts are what are analyzed), inference requires concepts (as we determine logical relations between them).
We could say that computers might simulate intelligent behavior in some way or other, but this is observer relative not an objective property of the machine, and it is a category mistake to call computers intelligent in any way that is coherent and not the result of projecting qualities onto things that do not possess them.
What makes all of this even more mystifying is that, first, the very founding papers of computer science speak of effective methods, which is by definition about methods that are completely mechanical and formal, and this stripped of the substantive conceptual content it can be applied to. Historically, this practically meant instructions given to human computers who merely completed them without any comprehension of what they were participating in. Second, computers are formal models, not physical machines. Physical machines simulate the computer formalism, but are not identical with the formalism. And as Kripke and Searle showed, there is no way in which you can say that a computer is objectively calculating anything! When we use a computer to add two numbers, you cannot say that the computer is objectively adding two numbers. It isn’t. The addition is merely an interpretation of a totally mechanistic and formal process that has been designed to be interpretable in such ways. It is analogous to reading a book. A book does not objectively contains words. It contains shaped blots of pigment on sheets of cellulose that have been assigned a conventional meaning in a culture and language. In other words, you being the words, the concepts, to the book. You bring the grammar. The book itself doesn’t have them.
So we must stop confusing figurative language with literal language. AI, LLMs, whatever can be very useful, but it isn’t even wrong to call them intelligent in any literal sense.
