Mathematically it's true. Anything that can be enumerated (that is, has an ontological mapping with the set of whole numbers) can be interpreted as input to some function which can be evaluated to some result also with an ontological mapping with the set of whole numbers. In other words, the entire human population could be a part of some program calculating the answer to some universal question, which may be about life, the universe, and everything. In fact, the answer may already be known. We're just one big server with massively parallel operation.

What we don't know is what that function is. Put differently, what is the question?
