Google are either completely delusional in thinking that at this point ML-based solutions are capable of replacing human decision making or they are fully aware that it's not working well and getting worse over time. It won't change though as savings made on humans are driving their YoY.

Pichai sacrificed (what was left of) Google's good press in favor of YoY. Google is proving time and again that they are unstable and unreliable as a business partner and can't be trusted with anything but being a growing stock market product.
