it's a big and beautiful idea. very challenging to solve. idea perfectly showing the imperfections of computers to deal with unmeasurable aspects of human life.
mostly, people's tears are silent and unplanned. people try to hide them, and certainly not to prove them....
maybe the one, bringing tears of joy, will need to find the "proof of tears", walking through this world doing good. just like in Acts 10:3
"He went about doing good"
if this would be the human setting, the big question would be - how to translate it into the digital domain? automated. measurable. exact. 0 or 1.
could the collective wisdom be a solution? is giving up automation and reviewing manually even an option?
