So...ya know Recaptcha Thing?
When a login asks you to prove you're not a robot by confirming a picture and typing the numbers of an address
For awhile that's how Google collected data for addresses for Google maps because they needed exact addresses, but couldn't decipher it from pictures. So they would ask you about a picture they knew, and then one they didn't.
The Google Earth co-creator low-key a friggin genius.
(Lol. Sorry just found this out from the Google Earth co-creator guest lecture and my brain is mildly blown)
