Matt's thoughts preshow:

We need an entire new academic field for post disclosure studies of every single subject.  This will demarcate an distinctly new era in human thought.

Who will found a College of Post Disclosure Studies - Alien History, Alien Ethics, Alien Amnesty, Alien Agendas, The 2nd Renaissance of humanity (for the rapid study, development, and release of advanced hidden science and technology)

Fascinating listens:
