&gt; Since the number of times it would be able to flip the bit changes due to random fluctuations in time due to context switching of processes, this generates an arguably truly random bit (I would love to see a PoC that shows otherwise, however).<p>This wouldn&#x27;t be true random. It&#x27;s just using the time jitter introduced by context switching to introduce entropy. Similar to many other pRNGs that use system entropy, mouse movements, etc in order to seed the pRNG.<p>A pRNG is &#x27;p&#x27; because if you know the conditions used, you can deterministically predict the outcome. The difficulty of recreating those conditions has nothing to do with being truly random.
