The interesting part is the human psychology behind it, i.e. what causes (allegedly) intelligent people to perform a necessary test, and then simply ignore the results of that test when the results aren't what they had hoped for? Were they imagining that the ocean would just give them a pass because they had made an effort?

But how can we know and verify the process they used to generate the random number generator?

Yes, how can we tell the difference between a true random number generator, and a device that is simply reading the next entry from a very long one-time-pad that our mortal enemies also have a copy of, and therefore can trivially "predict" future results from, no matter how perfectly random they are?

The original implementation of a working battery swap had been done by Better Place with an average swap time of about 5 min
Tesla later had a demo that was about the same with a side by side of a car being refueled. IIRC the Tesla swap was much quicker.
Tesla built ONE station at Harris Ranch and after about 2 years called the project a failure.
I assume they kept on collecting the extra CARB credits but i also assume that's only for Model S & X as rapid pack swapping on all their other cars isn't feasible

"how a battery swap system failed for Tesla when they tried it"
Elon had ZERO intention of actually building a swap network - it's was a smart ploy to qualify for more carbon credits as CARB had a tier for "quick refueling" that benefited technologies like hydrogen. I don't recall the exact details but the "refueling" time was impractical for EVs at the time if only using chargers hence the battery swap scheme.

all your points were considered by Better Place 20 years ago. you don't own the battery, you lease it.
they had 20 swap stations, mostly in Israel that kept operating for a couple years after the company officially went bankrupt.
they tried too hard, too soon & in the wrong market but they had a working solution
