Is everything random, or are at least some things logical? Whatever is random (e.g. noise, quantum fluctuations, radioactive decay, evolutionary genetic mutations, Kolmogorov randomness) is, in fact, universally unpredictable. — 180 Proof
Evolutionary genetic mutations are only random for human understanding. The chemical changes that are mutations are predictable (since they are chemical changes) and can be explained after the fact. Their effect on the changes of the structure or functioning of the superstructure, or of the organism, is also predictable, inasmuch as it is repeatable and accurately reflecting the same superstructure changes in the offspring of two similar organism pairs when the same DNA change occurs in both.
Radioactive decay is not random inasmuch as its rate is highly accurately predictable. I understand that the individual decaying elements can't be pointed out before they undergo the change.

I claim ignorance, and validly so, about noise, quantum fluctuations, and Kolmogorov randomness. I would like to think that there are probably causational, theoretically explicable functionalities to these movements, and there are completely non-predictable ones, such as picking the atoms whose nuclei will undergo change in radioactivity. In our macrophysical world everything is causational; it seems in the microphysical (quantum) world that is not true. I can't address that issue, as my knowledge is insufficient to have proper insight on that part of your argument.
Naturally I capitulate to your reasoning now, because I can't know whether what I am rejecting is true or not. Just remember, that, for instance, in an electron cloud around the nucleus we don't know where the electron is at any given instant (if electrons exist in the first place), but we know that all electron clouds in separate instances of a given element are identical in a given state of excitement.
One must be careful claiming randomness; when we say "where is the electron", we ask the wrong question, and claim randomness illogically, because the electron is distributed in the entire cloud, according to some probability function, and the electron as a unit never exists in a corporation anywhere in the cloud.
