Sophia’s defense against cheating is a joke. Using a program to detect irregularities in typing is a piss poor way to enforce test integrity. 

It’s a hand waive joke attempt. Sophia has 0 test integrity.

I am curious on what you base the above claim.  I'm told by someone internal at Google that they have apparently for years internally used a keystroke irregularity algorithm to ensure who (employees/contractors) are accessing their internal systems (in addition to other login/security procedures.).They have apparently had excellent success using this method, combined with others mentioned (IP, geolocation, etc) to accurately identify users.  Who is to say Sophia has not licensed the same or similar technology?
