Could you elaborate on how this is relevant to our day-to-day lives? That is to say, does alleged causelessness at a quantum level have any meaningfulness given we as humans do not exist at that level of organization?
In truth, cause-and-effect is something of an illusion on the macro level that we experience.
It's all probabilistic.
To put it another way, what are the odds of an event happening, if you take trillions of chances, and average the outcomes of those events?
The "outcome" will be whichever event has the highest probability of happening, even if the chance is only 50.000001%.
That's how probabilities work. The macro world is just the average outcome of trillions of quantum level events-- and it has the appearance of cause-and-effect, if you look at it that way.
Yet, it seems that we can depend on cause-and-effect over and over, right? Strike a dry match, and it lights-- the chemistry of phosphorous in an oxygenated atmosphere is pretty dependable.
Yet-- if you add up all the match-strikes in all of history, the total number is a tiny fraction of one millisecond's worth of quantum-level events in any random area larger than a closet...
In the final analysis, if Quantum Mechanics is a reasonably accurate model? Then cause and effect is an illusion.
However, it is a very convenient illusion, and in pretty much every case, we can depend on cause-and-effect in our everyday lives.
Mainly due to the fact we only exist for a brief candle-flicker in the history of the universe.
And by "we", that could easily be "you" or "me" or? The entire human race. All would be correct.
