But it is compatible with the data! The restriction makes the explanation
of the universe less complex. Why add more than necessary?

Why assume the physical world is non-computable, in absence of any evidence?

Ancient Greek philosophers may be of interest for historic reasons but
they don't offer any insights on "realities" and their "descriptions"
beyond those obvious for any kid with virtual reality experience.

Theoretical computer science offers a new philosophy based on formal
descriptions of realities and their descriptions and their observers.
No vague blabla anymore.
