Computers don't do random numbers well. Years ago I remember reading about one of the big tech companies using lava lamps to create truly random numbers (instead of pseudo random numbers). It's a neat story and I suspect that some variant of this approach is still in use today.

I’m so bad at shuffling cards that I end up arranging them in order again. Lol.

Wow! The probability for two people to shuffle the same deck? Crazy large numbers.

Yeah. That’s exactly the issue.

Cloud flare uses one, but they were patented by Silicone Graphics in the 1990’s. Called a Lavarand.

Lavarand - Wikipedia

en.m.wikipedia.org

All the one time pad ciphers for the Agency used to be generated by taking cosmic noise (leftover energy from the Big Bang) and turning it into letters and numbers.

Lots of ways to “get” random. But by definition a machine cannot “create” random because it’s a machine. So nothing about it can be random. It can only have the appearance of random.
