A tentative answer
Some simple ideas for spreading Systemic Innovation and Thrivability ideas.
By incorpotaring systemic innovation and thrivability (SIT) concepts in non-specific courses (something like "SIT for Lawyers" or "SIT for Medicine" or "SIT 101", etc.) professionals from all disciplines may be influenced. I believe that a large critical mass is needed for these ideas to cause an impact in society as a whole.
Universities may also help to spread the SIT approach when they do technology and knowledge transfer activities to other organizations, business, government organs, etc. While SIT ideas cannot be imposed, they may be spread if every (or at least most) activities include at least a minimum SIT content, for instance when defining the reference framework where the specific work will later be inserted.
More than long books, dense texts and web sites full of references and external links, a synthetic approach may be developed. In this manner, people who are not planning to be experts on this field can be approached and be influenced without creating a terminology barrier, or the impression that SIT ideas are for a specific elite of experts. The concept that "SIT ideas are for all mankind" requires reducing the terminology gap; and delivering a concise message which can be understood by laypersons.
