Relationship between BEM and atomic/functional CSS?

[nghkhoi]

Sorry if this question could be somewhat silly, I'm just a new learner.

I can see that applying BEM to styling will overally improve code quality in many aspects.

However, the current trend is seemingly moving towards atomic/functional CSS.

In my understanding, it is the so called global modifier once addressed in the FAQ section here: http://getbem.com/faq/#can-i-create-global-modifier. Perhaps in a different context?

I wonder what the most recent viewpoint on relationship between these two powerful CSS methodology is?

Perhaps some experienced user can elaborate on some actual way to combining BEM and atomic/functional CSS?

Thanks and regards.
