The goal isn't to stop judging - it is to judge better.
You just summed up in a single sentence. We all do judgements, like you mentioned in your post. But we tend to stick to thoughts, ideas and pass events when lookin to present events, and even future predictions.
The human "machine" is quiet complex, but very logical in terms of biological survival.
Yet, our heads get in the way of natural logic and conflate our thoughts with reality.
