Back in 2016 when this video of Sean Carroll speaking of his Mad-Dog Everettianism was seemingly made, people were not as aware of computer algorithms as they are today.
What computer algorithms demonstrate is the necessary, behind-the-scenes, algorithmic processing steps (performed by human beings or computers) required to turn equations into part of a viable system. These necessary algorithmic processing steps can’t be dismissed or hidden under the carpet.
So, contrary to Sean Carroll’s claim (which mightn’t have been on this video) that Mad-Dog Everettianism is a minimalist solution to the problem of quantum mechanics, the behind-the-scenes algorithmic processing steps required to attempt to implement Carroll’s Mad-Dog Everettianism is anything but minimalist.
The issue is: to this day, physicists (and mathematicians) seem completely incapable of seeing or acknowledging that, without the aspects of the world that can only be represented as algorithmic steps, equations can never represent a viable system.
Algorithmic steps are represented by statements containing the following types of symbols: IF, AND, OR, IS TRUE, and THEN. These symbols (IF, AND, OR, IS TRUE, and THEN) represent time-place point-of-view aspects of the world that are necessary in order for a viable, moving, world to exist.
These necessary aspects of the world, represented by IF, AND, OR, IS TRUE, and THEN, are entirely different aspects of the world to the aspects of the world represented by equations. These necessary aspects of the world, represented by IF, AND, OR, IS TRUE, and THEN, CAN'T be represented by equations.
