One language that was not on the presenters list is SQL, very popular, but not OO nor functional.
One thing lot of programmers do is to abstract SQL to OO style, even though SQL describes a relation that can be computed to a result, in some way similar to a function, but it seems that most prefer to look at is has a state, even though it doesn't.
Sure, the tables where data is stored has a state, but the sum of the tables is a relationship in time & depending how you look at it you get different results. It is very hard to map relationships to OO correctly.
It is probably easier for most people to think about the world as set of things rater than a relation in time. Many of our natural languages are organized around things.
