Current state of face classification?

Hello Community.

I just wanted to ask what is the current state of real-world face classification systems? I am not into the field much, but after talking with a few people the opinions ranged from real-world face classification being difficult to it being no longer relevant or difficult (since the re-birth of deep architectures).

So what is the current state of this problem? I read some papers, but there are so many of them that I am not even sure whom to trust.

Thanks a lot for your time.
