How unique ARE your fingerprints?

Are no two fingerprints truly alike? Perhaps your fingerprints are more like each other than they seem. Go on, take a minute, look at your fingers! Then find out the results when we ask a computer that same question...

Your videos are always so hecking interesting! :D I always learn so much!* I never manage to catch your early (for me) streams, so it's a delight when I see them appear on youtube. (It's Abyssal_Icarus from twitch, one day I will sort out my multiple online identities.)
*Disclaimer: my trash fire brain immediately ejects the information into The Void, because short-term memory whomst? BUT I enjoy learning the things while I'm learning them, and bonus! I can learn them again, so that's fun :)
Random trivia: Koalas have almost-human fingerprints, and could potentially contaminate a crime scene. No, their prints won't give a false positive, but they are similar enough that an investigator might spend a long time trying to find the other "people" present at the scene with no results.
Further random trivia: I have ME/CFS, and I'm gradually losing my fingerprints. It's apparently fairly common for ME/CFS, so that's "fun". I would be curious to know if these algorithms could be trained in future to find early signs of certain diseases (several other conditions also tend to have fading prints) Probably not, but kind of interesting, to me anyway :)

My grandfather was involved in early fingerprinting for the uk police in the 1950s - so great to hear this.

Finger for the finger god! Print for the print throne!
