As I mentioned in my late comment on your post from 8 days ago, I worry, as an educator, how it may become more difficult to teach these concepts in the future. I am super positive about the inevitable influence blockchain will have on education, especially in terms of online ed, and from there, cost, overall value and efficiency, etc, but I am less positive about the overall ability to help thousands of students to develop better critical thinking skills. I teach communication classes, which are very well suited for this today, but I find that the deepest learning in regard to critical thinking in communication comes from face-to-face classroom interaction, which is already degrading rapidly. Less students want to be in classrooms at all, and they sign up for live classes grudgingly. This is partly what has led me to take a proactive approach to online education (wasn’t that long ago I argued against it!) but it’s also troubling. Glad I found your blog. You’re doing a better job than me here, but our posts on such topics are on the same page. Cheers.
