These kinds of ponderings are extremely unconvincing and logically untenable.

Notions of:

Simulation

Program

Programmer

(or anything that refer to the human brain or consciousness in computational terms)

are all artificial, derivative concepts borne out of the human imagination. And they all carry meanings established in specialized industries.

So what is the justification to then shuttle those terms into metaphyics and cosmogonies that transcend any historically recent technological and cultural concepts borne out of certain human imaginations? That's logically the thing as some bored nerdy kid one afternoon slapping together a paper mache orrery with dangling Pokemon characters, and declaring "This! This explains our reality!"
