I tend to believe &quot;them&quot; when &quot;they&quot; say that a modern CSPRNG can generate essentially infinite, random-looking noise from like a 256-bit seed-o-randomness. This device would be a great seed, on boot for example. It&#x27;s also highly reliable because it simply cannot be hacked (although a truly paranoid person would also want to connect an <i>analog</i> oscilloscope and compare the output to what you see on your computer.)
