Do LLMs *understand* language? Do educational AI agents *understand* the material they teach (or their students)? Claims about what AI systems do or don't understand are pervasive, but assessing them requires an account of MACHINE UNDERSTANDING

The biggest reason we don't actually have a "replication crisis" is that science is a process of advancing what's working, and not fixing what hasn't. Sometimes it's slow, and we backtrack a bit. But it's never stalled. That said, the strain on scientific publishing is generating a lot of crap.

What is computation? ("The Brain, in Theory", chapter 4)
A computation is essentially an effective method in a formal domain (as opposed to a domain of interactions with the world), generally in the domain of numbers, which can be applied by a human with just pen and paper – we will see in chapter 8 the significance of this detail. Clearly, a recipe is not a computation. […] A computation operates on data (not pasta). It has an input and output, and it implements a particular mapping from input to output by a sequence of steps that belong to a finite set of elementary operations on symbols. The latter restriction is crucial for the notion of computation. Otherwise, the concept of computability would be totally meaningless. For example, Alan Turing demonstrated that there is no program that can take another program as input and calculate whether that program eventually stops: the halting problem is not computable. Obviously, this theorem would be false if we were allowed to choose any kind of instruction (choose as an instruction the mapping that assigns a stopping / non-stopping label to programs). Therefore, a process can only be meaningfully called “computation” when it is composed of a finite set of elementary instructions. Otherwise, the process is just a mapping between different kinds of data, not a computation.

We propose a new neural architecture, “Continuous Thought Machines” (CTMs), which is built from the ground up to use neural dynamics as a core representation for intelligence. By using neural dynamics as a first-class representational citizen, CTMs naturally perform adaptive computation.
