I don't think it is techies at this point - more hanger-ons marketers given the complete lack of requisite understanding or interest in it and pushing a solution based on how good it sounds instead of how well it works.
Even by the standards of machine learning which has often been guilty of following spurious correlations. Anyone who actually worked with it would laugh like an artilleryman hearing Aristotole's impetus theory because it is so obviously disconnected from reality.
I have cynically theorized it is deliberate "bias laundering" ever since I heard of a defacto classist British algorithm which included /garden size/ (yard in American sense).
There is literally no legitimate reason to include it in a reoffense risk as a variable. Even if they thought it somehow had a rehabilitative effect then ownership shouldn't be a variable when they can just turn them into upstanding citizens through yardwork!
