It's unlikely to have ever happened.

2^42 is 25 times the total number of people ever born in all of history.

...i think it's quite a bit more than that

I got 38x with 117 billion total people. Not sure where OC got their number, but it's kind of in the ballpark, so maybe it was just shitty mental math.

getting correct within a factor of 2 after a 42-fold exponentiation would be amazingly good mental math

[–] AeroLemming@lemm.ee 2 points 1 year ago

The easiest way would be to say 117 billion is ~2^37 because 2^[7, 10, 20] are 128, 1024, and about a million (1024*1024), so multiplying those all together gives a little over 128 billion, which is pretty close to 117 billion. So, 2^42/2^37=2^5=32. Pretty close, all mental math. Granted, it does require you to either memorize or compute powers of 2 up to 10.

I made a typo and used 177 b.

I had to check the math and I was surprised that 2^42 is “only” 4.4 trillion. Thought it would be a lot greater like there are less atoms in the universe similar to the uniqueness of a shuffled deck of cards.

Also, twins aren't identical copies either. Different fingerprint etc.

Fingerprints aren't genetically coded, and clones wouldn't have the same fingerprints, either.

I typically associate "clone" with "an exact copy", with the same exact molecular layout and even thoughts. So a literal exact copy. Clones on a DNA basis, so something possible for years, would indeed be different in some details.

The definition of "clone" you believe in is science fiction nonsense. Why believe in nonsense when the scientific definition of clone is different?
