What is the teacher’s role in 21st Century?

It’s interesting how the role of professor has changed and how politicians view the role of professor:

It is the role of the professor, Plato said, to enter the cave, round the bend, unchain Man from his wall and lead him out into light and life.

Plato used the word “professor,” but a new word arose in late Middle English, from the Latin verb “educere,” meaning “to lead out”: educator.

Educators, therefore, share a noble calling: To lead chained intellects out of their darkness and into light.

So what is the role of the teachers in the 21t Century?
