Robert Shiller's lack of familiarity with ICOs, as highlighted in this article, disqualifies his position on Bitcoin. "The conversation was edited and condensed for clarity." Shiller was unprepared to discuss Bitcoin.
Wouldn't it be better to ask if his position is any different, now that he has had time to research the topic? It would be helpful if you could provide material info to Mr. Schiller that he does not have, beyond the ICO revelation, so he can re-assess. You clearly have important info that he could use.
ICO's are now a core application to the cryptocurrency ecosystem and have thereby driven growth to Bitcoin. Let us know if there is anything else I've missed. Your communication techniques are exemplary.
