The best teachers are also the best students. Therefore, the label "teacher," at least in terms of being/consciousness, is redundant.

So many doors are open that what is occurring is happening and won’t take 200 years without or with teachers. 

The teacher-guru/student-follower model is slowly being replaced with the "we're in this shit together" model. Let's journey together. I think you are right, the students dare to challenge the teachers and we will invoke conversation! 

I really hope so.

The second model is the default for everyone who does not find a teacher. But it is not optimal. As Rumi put it, 

"Without a guide, the journey of two days takes two hundred years."

I like that 'model' as it seems more honest, authentic. After all, we're all on the same journey. As Oscar Wilde said, 

"We are all in the gutter, but some of us are looking at the stars".

It seems 'models' are dissolving too, replaced by trust in what appears and how one is moved.
So be done with role models and be yourself, accept yourself and you will find yourself accepting others with mutual affirmation.

Friends in Presence as Jen Peer Rich says.
