>>10757806If anything could possibly be considered evidence for "true randomness," it's QM. We've been performing experiments on quanta for more than 100 years, and the results of measurement are still best described by probability distributions.
Compared with the early to mid 20th century, we can control for just about everything: single atom traps, ultrahigh vacuums with mean free paths of many kilometers, temperatures a few billionths of a degree above 0K, single photon sources, vastly improved materials quality, vastly more sensitive detectors, etc, etc, etc.
Classically, we really should have seen some hint of determinism by now.
