Is consciousness an epiphenomenon?

Continuing this post, Dehaene answers no starting at 19:55. Consciousness is required for the following operations:

• To reflect upon information: subliminal information is evanescent, while conscious information is stable.
• To discretize the incoming flux of information to a few samples that can be reported or stored.
• To route this information to other processing stages, thus performing chains of operations.
• To monitor our behavior and correct our errors.
• To share the information and achieve collective decisions.
