I watched through the video and I still cannot tell "What Physicists Don't Want You to Know About Quantum Mechanics". They seem to be hinting that the Copenhagen interpretation is being kept a secret for some reason, but that's not true, it isn't a secret by any means.

This video seems to be a (philosophical) commentary on social aspects of science by comparing it to the contrasting worlds of general and quantum.

I'm confused, but it might be because of the (potentially poor) title.
