If the point is "who knows what a blockchain is", I will agree. On various opportunities we meet bank employees not dealing with IT development. They heard about Bitcoin or some other cryptocurrency and then ask us what a blockchain is and if blockchain is a serious trend.  They usually don't have an idea what blockchain is. Or even worse they heard a little bit about blockchain an tell crazy things about blockchain :-). 
I appreciate your answer. It helped me to better understand who was doing the survey.
