Perhaps he was simply being modest. "UI design, programming, and product strategy" are just the three specific subjects he has felt qualified to "long argue" about.
I don't know about modesty, but it's correct that I was limiting myself to subjects that I know about. We have a shortage of truly great software designers and coders. So I think it's important that we shore up our methods for passing on knowledge and experience in these areas. If we treat it like somebody else's job, or academia's job, then we won't see the improvements that we want to see in conference quality, applicants for our job openings and so on.
Ever since I have watched your videos and read your blog, I've learned more about UX/UI than ever before. I don't think people realize how hard it is to find good content when getting started in the field. You hear about a lot of big name designers and UX/UI guys and try to learn from their twitter/blog but no one teaches like you do. I really appreciate your philosophy on teaching and honestly can't express how grateful I am for the content you have shared. If we meet someday I am definitely going to buy you a beer :)
