I mean, ya, if that’s how you wanna define a soul, I’ll say that exists.

As for the more common definitions which tend to extend to moving that software around and that software moving to the cloud in the case of a system failure, I have no reason to believe the brain has wifi, gps, or satellite functionality.

But if we simply describe it as “the software on the brain”, I hold no objection and can comfortably say it exists.
