Most definitely write a book and Sprlnblg above has it right, maybe give it a brief 100-year outlook... And, I would lean towards an e-book -save a few trees, affordable, etc.
For now, a very big "THANK YOU" for your refreshing writing and observations on very large and complicated subjects. You have been bookmarked!
Never write a book with an experation date. In the unlikely event you actually have something to say make it timeless.
