It's also complete and utter bullshit: https://m.youtube.com/watch?v=VTsBP21-XpI
TL;DW: CAPTCHA isn't designed to identify if you're a human, it's designed to identify which specific human you are. And if it can't do that (because you're not already part of the AdSense ecosystem making Google money), they force you to do free labor by helping Google train their image identification algorithms.
- There are of course other services.
  The main one being hCAPTHCHA, which does have its own problems namely it being terribly inaccessible for anyone with vision problems and also it's images are overly americanized but at least you're not training some AI.
was it named by a bot?
- By an engineer 😎
  
  a human engineer?
I learned this the other day and assumed it had to be a prank at first. What a wild name.
- I heard it from Sandi Toksvig, she wouldn't lie to me.
  
  Hmmm sounds like a made up name. You might have been swindled
- Almost guaranteed to be a backronym.
Shame it doesn't do the CHA anymore
"Public"
- Public for use, not for knowing how it exactly works. You might call it proprietary, if you're so inclined.
  
  So like public schools in the UK?
And it’s complete trash.
I thought it meant the Captain doing a Cha Cha Real Smooth.
I only trust the Voigt-Kampff test.
Uh Oh, the A doesn't make the same sound as Automated. Is Chris Hardwick gonna have a breakdown?
