Re: this matters more than people think
"you would think with all that interaction with nature the opportunities to seed would be endless"
But they'll try something like "I know, lets just record some noise from the antenna, RF noise is bound to be random!", but once the device is in the outside world, it then turns out that recording direct from the antenna actually produces an easily reproducible sequence because it was just picking up the harmonics from someone's microwave oven (for example).
Making actually random numbers is hard, you're better off just using 4. It's definitely random because I rolled a dice, and now you can use it too.
