One very productive idea is education of MIC workers. The advantage of educating MIC workers is two-fold:
These people are typically very secret. So education of them about aliens may not immediately translate in global panic.
These are people in control positions in society. Educating them about aliens will help open and transform society.
Also, many MIC workers are already aware of aliens; it will be easier to have them open to the alien education.
MIC = military-industrial complex
