Jeff A/B testing is, incidentally, what the universe uses when turning tables into chairs with a lot less than sandpaper. It's called evolution. We can argue whether the universe has a soul or not, but I think it's basically honest. But your essay is still good! We don't have time to play universe with our lives. And the monads that fill our hearts as this world turns (where they break and get twisted and eventually stop) will vibrate all the more sweetly if we stop pretending that we can judge the effects of our agency much and just try to connect ... using our hearts, and minds and souls and all the ingredients of what make us humble humans, not the cosmos, let alone machines.
