AI is like all other programs; execution of predefined tasks, no creation of new knowledge to solve novel problems.

AGI = universal problem solver; creates knowledge. Opposite of not creating knowledge.

BTW, perfect value alignment is neither feasible nor desirable.

Yeah those with side effects transform minds, and, if they get a mind to act, the world.

The motivation for treating ideas as functions is to solve the problem of how to encode ideas in a computer program.

Ideas need not return the same output for same input, nor do functions.

So the explanatory universality of people is powered by the computational universality of functions. Those two universalities are deeply intertwined.

Since Lambda Calculus is computationally universal, all ideas in the mind can be expressed as functions, and so the above is the same as saying that it’s a functional replicator in a mind that explores the space of all possible functions.

A more elaborate one: ideas replicate imperfectly within a creative mind and thereby inadvertently explore the space of all possible ideas. This is how sometimes ideas evolve in a mind that happen to solve a problem/explain something.

Some quick arguments for the explanatory universality of creative minds:
