Educators here are equivalent to actively creating a dominant tone with available knowledge and ideas, and establishing an absolute authority in the hearts of many universal recipients of knowledge and ideas. This authority is imprisonment, blind obedience and absoluteness.

Therefore, "educators are not creating gods" is to express the idea of not imprisoning.

The "stone statues" here are like mechanized sculptures that have been carefully designed and carved.

"Education is not to build a stone statue" can be understood as not to be stereotyped and stifle creativity and imagination.
