A CX PM attended one of my teams inspect and adapt sessions where we were showing a machine learning model to help determine based on weather patterns, water levels and usage information to identify the most likely places leakages on the clean water network may hit during adverse weather events. 
He asked how we can ensure that our machine learning model wouldn't learn too much and try to take over the rest of the platform. 
Trying to explain to someone that a machine can only learn from the data it has access to and all that it could do was predict outcomes based on data when that person thinks we could create a fucking terminator was terrifying, hillarious and hugely frustrating. 
So yes I agree, this man asking how we could ensure we didn't accidently start skynet was a stupid question.
