Consequence of a 2-document collision is big enough, that a

Nostradamus is all they could come up with, which is laughable.
If they upgrade this to an actual partial 3.6-bit preimage
attack, and one collision takes 2 days as they say, for a
comparison, with such partial preimage attack, full preimage
attack on a 32-bit hash like crc32 will take 2^^(32-3.6)*2 days
= 1959870 years in an ideal case.
By the way, I didn't respond to this, but I suppose I should.

Hence why you should keep your butt out of cryptography
discussions until you take any class on it at the very least.
Your calculation is garbage and shows how you haven't a single
clue about what you are talking about.
Again, you can have the last word, but I'm certain I'm done here
regardless. If you can't see the fact that you aren't smarter
than the experts by now (with the above) then I don't think I can
convince you with my words. Experience is the best teacher
sometimes. I just hope that I never accidentally use a program
you write expecting my data to be secure.
