Atoms are mostly empty space, material reality is to an extent an illusion. Leave it up to modern science that has come to believe itself innately opposed to diety, to theorize that it’s some great cosmic comuputer, no doubt self-organized over trillions of years.
Their theory is interesting. If you discount God and purpose in creation (I don’t), then consider the odds of actually being alive during this portion of civilization (based on the number of people that have been alive, are alive and will be alive in the future, it is very unlikely that we are actually living right now. They don’t claim that the computer self organized but rather is created by our descendants to recreate earlier times.
It is an interesting though experiment.
