This is partly the reason they fired him. There is no well defined scale of sentience. While trying to create that scale, using email/chat history of all Googlers they found Managers acting the most robotic and efficient while handling well known trained for situations, but totally unimaginative, bordering on mindless when handling untrained for situations. This put the managers at the bottom end of the sentience scale. As you can imagine, if you aren't a manager atleast, the study was shelved and the team reassigned to improving lock screen notifications or whatever. But as soon as Blake's post went viral people started asking what happened with the sentience scale work? Those conversations had to be stopped.
