I fully agree, random today means one of the following <i>very</i> different things:<p>- we know with certainty that it follows a &lt;xy&gt; distribution and there is no way we could know more<p>- we don&#x27;t know enough so it appears random to us.<p>If I were forced to bet on one of these, I&#x27;d say it&#x27;s always the latter except in the case of Heisenberg uncertainty.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Uncertainty_principle" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Uncertainty_principle</a>
