I still think it insane. We have falling crime rates and we still arm ourselves as fast as we can. Humanity could live without face recognition and we wouldn't even suffer any penalties. Nope, people need to sell their evidently shitty ML work.
(2) Your argument strikes me as somewhat similar to "I feel fine why should I keep taking my medicine?".

But "things are getting better so we should change what we're doing" is not a particularly sound logical argument.
